4 Inch Screw Type Wheels with Brake

Adding mobility to your heavy furniture, workshop equipment, or utility carts should not mean sacrificing stability. Our 4 Inch Screw Type Wheels with Brake deliver the perfect balance. You get smooth, effortless movement when you need it, and rock-solid stability when you do not.

These heavy-duty casters feature a threaded stem design. It screws directly into your furniture legs, providing a clean, professional look with secure attachment.

The 4-inch wheel diameter is the sweet spot for versatility. It is large enough to roll smoothly over thresholds, carpet edges, and minor obstacles. Yet it is compact enough to maintain a reasonable profile beneath your furniture.

Whether you are outfitting a workbench, mobile cart, or heavy cabinets, these casters provide the performance and control you demand.

Understanding Screw Type Casters with Brake

Screw type casters, also known as threaded stem casters, feature a metal rod with precision-cut threads. It screws directly into a threaded insert in your furniture leg.

This design offers distinct advantages over traditional plate-mounted alternatives. It provides a clean, professional appearance with no visible mounting hardware. Installation is quick and tool-friendly. You simply screw into place.

The secure attachment resists vibration and loosening. Easy replacement makes upgrading or replacing worn casters simple.

Our 4-inch models feature full 360-degree swivel action. This allows you to change direction instantly and maneuver in tight spaces. The swivel head responds immediately to changes in direction, making navigation effortless even with heavy loads.

Advanced Brake Systems for Complete Control

The brake feature transforms these casters from simple wheels into true mobility solutions. Depending on your specific needs, our 4-inch screw type wheels are available with several brake configurations.

Top Lock Brake places a positive locking force directly against the wheel tread. This simple, effective mechanism prevents the wheel from rolling when engaged. A foot-activated lever makes operation easy. Just press down to lock and lift to release.

Dual Lock or Total Lock Brake is for applications requiring maximum stability. Our dual-locking casters feature a total lock brake that simultaneously locks both the wheel and the swivel mechanism. When engaged, this system prevents rolling and swiveling. It creates an exceptionally stable base for workbenches, medical equipment, or any application where movement during use could be dangerous.

Posi Lock Brake is similar to the top lock brake in function. It places locking force against the wheel tread but features a pedal located above the wheel rather than on the side. This design can be advantageous in certain mounting configurations.

Heavy-Duty Construction for Lasting Performance

Built to handle demanding applications, these casters feature robust construction that ensures years of reliable service.

The caster housing is manufactured from heavy-duty steel with a zinc-plated finish. This provides excellent corrosion resistance. This finish ensures the casters maintain their appearance and structural integrity even in challenging environments.

High-quality ball bearings are integrated into both the swivel head and the wheel hub. This dual-bearing design ensures smooth, effortless rolling and rotation. It significantly reduces the effort required to move heavy loads.

Impressive Load Capacity

These 4-inch casters are engineered for serious weight-bearing. Depending on the specific model, each caster can support different capacities.

Standard duty models support 200 to 250 pounds per caster. Heavy-duty polyurethane models support 350 pounds per caster. Total set capacity for 4 casters ranges from 800 to 1,400 pounds.

Always calculate the total weight of your furniture plus its typical load. Ensure the combined capacity exceeds this by at least 25 percent for a safety margin.

What stem sizes are available?

Selecting the correct stem size is crucial for proper installation. Our 4-inch screw type wheels with brake are available in several common thread sizes to fit a wide range of applications.

1/2″-13 UNC by 1-1/2″ is the standard American size. It is ideal for heavy-duty furniture and equipment. 3/8″-16 UNC by 1-1/2″ is a smaller diameter, suitable for medium-duty applications.

12mm by 1.75mm pitch by 1-1/2″ is a metric option for international equipment. 10mm by 1.50mm pitch by 1-1/2″ is a metric option for lighter-duty applications.

Each caster includes a nut and lock washer for secure attachment. This gives you the flexibility to either screw directly into threaded inserts or mount with hardware.

How do I measure my existing stem?

If you are replacing old casters, follow these simple steps.

First, remove the existing caster from your furniture. Second, measure the stem diameter using a caliper or ruler.

Third, count the threads per inch for imperial or measure thread pitch for metric. Fourth, measure the stem length from the base of the stem to the end.

Fifth, note whether the stem is threaded the entire length or only partially.

If you are unsure, many manufacturers offer measurement guides or customer support to assist.

Premium Wheel Materials for Every Application

The wheel material significantly impacts performance, noise level, floor protection, and suitability for different environments.

Polyurethane wheels offer an excellent balance of durability and floor protection. Benefits include quiet operation with shock-absorbing properties. They are non-marking and will not leave scuffs on hard floors.

They offer excellent durability with resistance to wear. They roll smoothly on concrete, tile, and wood surfaces. They have a load capacity up to 350 lbs per caster.

The polyurethane tread has a durometer hardness of approximately 55D. This provides the right combination of firmness and cushioning.

Thermoplastic Rubber wheels excel at providing cushioned rides and maximum floor protection. Advantages include superior vibration absorption for sensitive equipment and near-silent operation.

They provide excellent traction on smooth surfaces. They are non-marking and non-staining. The soft tread of 70 to 80 Shore A provides gentle floor contact.

These wheels perform exceptionally well on hard surfaces like concrete, tile, and wood. They will not mark or mar floor surfaces.

Nylon or Phenolic wheels are for specialized applications requiring maximum chemical resistance or exposure to moisture. They offer distinct benefits including superior resistance to water, steam, and cleaning agents.

They provide excellent chemical resistance against corrosive agents. They feature rust-proof construction when combined with stainless steel hardware. They have a load capacity up to 300 lbs per caster.

How do I install these casters?

Installation is straightforward and requires minimal tools.

For furniture with threaded inserts, first ensure the threaded insert matches the stem size and thread pitch. Screw the stem into the insert by hand until snug. Use a wrench for final tightening if needed, being careful not to overtighten.

For furniture without threaded inserts, first drill a hole of the appropriate diameter for your stem. Insert the stem through the hole. Secure with the included nut and lock washer from the opposite side.

Some applications may benefit from using thread-locking compound for added security, especially in high-vibration environments.

What is the total mounting height?

When installed, the 4-inch casters provide a total mounting height of approximately 5-1/8 inches or 130mm. This measurement includes the wheel diameter plus the caster frame and stem length.

Be sure to account for this when planning your project to ensure proper furniture height.

Versatile Applications Throughout Your Space

For material handling, they are ideal for utility carts, service carts, platform trucks, and warehouse equipment.

For furniture, they work on heavy cabinets, entertainment centers, shelving units, and kitchen islands.

For medical equipment, hospital carts, medical stands, and patient room furniture benefit from stainless steel options with total lock brakes.

For DIY projects, they are perfect for custom furniture, plant stands, mobile bases, and workshop creations.

Should I get all casters with brakes?

For most applications, a combination works best. Consider these configurations.

All four locking provides maximum stability but requires releasing all four brakes to move. This is ideal for workbenches or equipment that stays put most of the time.

Two locking and two swivel is the standard configuration for carts and furniture. Place the two locking casters on the same side for parking brake functionality.

Total lock brakes are essential for applications where any movement could be dangerous. They lock both wheel and swivel.

Choose the Right Caster for Your Needs

When selecting your 4-inch screw type wheels with brake, consider these factors.

First, consider load requirement. Calculate total weight plus safety margin. Second, consider stem size. Match your existing threaded inserts or planned mounting method.

Third, consider brake type. Choose between top lock for wheel only or total lock for wheel plus swivel. Fourth, consider floor surface. Choose polyurethane for durability or TPR rubber for quiet cushioned ride.
