Value Collection 93056 Button Cap Screw 4-40 3/4in 18-8 Ss 50pk

Product Description

The VALUE COLLECTION 93056 is a 4-40 button socket cap screw designed for precision fastening applications in mechanical assemblies, enclosures, and equipment panels. The button head profile provides a low-profile, finished appearance and is driven by a 1/16-inch hex socket. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion in mildly wet or humid environments. The screw is fully threaded with a 3/4-inch length under head and conforms to ANSI/ASME B18.3 and ASTM F837 standards. Each package contains 50 pieces.

This fastener is suited for use in HVAC equipment panels, electrical enclosures, plumbing fixtures, and general mechanical assemblies where a flush, low-profile head is required. The 4-40 UNC thread pattern is a standard fine-pitch inch thread commonly found in light-duty machine fastening. The 18-8 stainless steel construction makes it appropriate for indoor and light outdoor installations where mild corrosion resistance is needed without the cost of a higher-grade alloy.

Installation Notes

Installation requires a 1/16-inch hex socket key or ball-end hex driver. Ensure the mating threaded hole is clean and properly tapped to 4-40 UNC before installation. Do not over-torque small-diameter stainless steel fasteners, as the alloy is susceptible to galling. Always de-energize and lock out electrical or mechanical equipment before fastener service on live assemblies.
