Value Collection 88547443 Cup Point Set Screw 10-32 Grade 8

Product Description

The VALUE COLLECTION 88547443 is a Grade 8 steel cup point set screw designed for secure, non-permanent fastening in mechanical assemblies. Threaded 10-32 UNF with an overall length of 3/16 inches, this fastener uses a 3/32-inch hex drive and features a hardened cup point that bites into the mating shaft to resist rotational and axial movement. The black oxide finish provides a moderate level of corrosion resistance and reduces surface reflectivity. Each package contains 25 screws. This screw is installed by licensed machinists, millwrights, HVAC technicians, and other trade professionals who need a reliable, high-strength headless fastener for set-screw applications.

Cup point set screws in the 10-32 thread size are common in light to medium-duty mechanical applications including motor shaft collars, pulleys, sprockets, knobs, and HVAC blower wheel hubs. The 10-32 UNF thread standard provides fine-pitch engagement suitable for thin-walled bosses or precision components where coarse threads are not appropriate. The Grade 8 material rating indicates a high-strength steel construction capable of handling significant clamping loads in demanding service environments.

Compatibility

Designed as a standard 10-32 UNF cup point set screw suitable for shaft collars, pulleys, blower wheels, sprockets, and other mechanical assemblies requiring a headless fastener with cup point contact.

Installation Notes

Install using a calibrated 3/32-inch hex key or T-handle Allen driver. Ensure the mating shaft or bore is clean and free of debris before seating the cup point. De-energize and lock out any equipment before accessing rotating components. Follow applicable mechanical and electrical codes when servicing equipment that incorporates these fasteners.
