4 inch screw type wheels -breaks

4 Inch Threaded Stem Swivel Caster with Brake.

The AAGUT 4 Inch Threaded Stem Swivel Caster with Brake is a professional-grade, heavy-duty mobility solution. It is engineered for industrial workbenches, rolling carts, large machinery, wire shelving, and commercial equipment.

This 4-inch screw-type caster features a precision-threaded 1/2″-13 UNC x 1.5″ stem. This is the standard US coarse thread specification for high-load applications. It provides a secure, vibration-resistant mounting platform.

Each caster wheel is constructed from solid, non-marking rubber bonded to a heavy-duty steel or polypropylene core. It delivers smooth, quiet, and floor-protecting roll across concrete, epoxy, tile, and hardwood surfaces.

The 360-degree swivel head incorporates dual precision ball bearings. This ensures instantaneous directional response and exceptional maneuverability even under heavy loads.

A robust, side-mounted cam brake engages directly on the wheel tread. It provides reliable stopping power and secure stationary positioning when engaged.

With a remarkable 330 pounds capacity per caster, this caster delivers the durability and performance required for demanding environments. The complete set includes four heavy-duty casters, all equipped with brakes.

What Does 1/2″-13 x 1.5″ Mean and Why Is It Critical?

This specification defines the exact thread geometry of the stem. It is the single most important factor in determining compatibility with your equipment.

1/2″ is the major diameter of the threaded shaft. -13 is the thread pitch of 13 threads per inch. 1.5″ is the length of the threaded portion from the shoulder of the caster.

You must verify that your equipment has threaded sockets or accepts this exact stem specification. This product is NOT compatible with other thread sizes or metric threads.

Attempting to force an incorrect thread will strip the socket and destroy the caster.

What is the Difference Between a Wheel Brake and a Total Lock Brake?

This 4 inch screw type wheels -breaks is a critical distinction that affects functionality. This caster features a wheel brake ONLY. The side-mounted cam lever presses against the tread of the wheel, preventing rotation.

However, this brake does NOT lock the swivel mechanism. The caster head will continue to pivot 360 degrees freely even when the brake is engaged.

4 inch screw type wheels -breaks is the correct configuration for workbenches and tool carts that need to stay in place but be easily repositioned. It is also ideal for wire shelving that must remain stationary but requires steering.

This is NOT suitable for precision machinery that must be completely rigid. It is not suitable for medical equipment requiring absolute stability. For total lock functionality, you require a caster with a dual-function brake pedal.

What Surfaces Are These Casters Suitable For?

This caster features a solid rubber wheel specifically formulated for multi-surface industrial and commercial use. The non-marking rubber compound provides excellent traction.

4 inch screw type wheels -breaks prevents slipping and sliding on smooth surfaces. It will not scuff, mark, or damage sealed concrete, epoxy, tile, or hardwood. It reduces vibration transmission to sensitive equipment.

4 inch screw type wheels -breaks is significantly quieter than polyurethane or hard plastic wheels. These casters are verified for use on warehouse floors, workshop concrete, retail environments, and finished residential floors.

They are not recommended for soft or deep-pile carpet.

What is the Verified Load Capacity?

The static load capacity per caster is 660 lbs. The dynamic load capacity per caster is 330 lbs. This is the safe working load for rolling applications.

The 4 inch screw type wheels -breaks set of four total capacity is 1,320 lbs. This assumes even weight distribution and a level floor. These ratings are verified by the manufacturer.

They are consistent with industry standards for 4-inch heavy-duty stem casters. User reviews confirm successful application under large industrial planers and heavy machinery bases.

How Do I Install These Casters?

Installation is straightforward but requires verifying thread compatibility first. Inspect your equipment and identify the threaded sockets or holes.

Confirm the thread match by testing the stem in the socket by hand. 4 inch screw type wheels -breaks should thread smoothly without resistance. Do not force it.

For pre-threaded sockets, simply screw the caster in by hand until snug. Use a wrench on the integrated hex nut to tighten securely.

For through-hole mounting, drill a 1/2″ clearance hole. Secure the caster using the included lock nut and washer from the opposite side.

Ensure all brake pedals are positioned for easy access.

What is Included in the Package?

4 inch screw type wheels -breaks package includes four 4-inch threaded stem swivel casters with brake. It includes four mounting lock nuts for through-hole applications. It includes four flat washers and an installation wrench.

4 inch screw type wheels -breaks set includes four casters, all with brakes. Some competing products only include two brakes per set. This set provides complete 4-corner braking.

What Are the Key Limitations?
