Value Collection A98125 8-32 X 1/2 Button Head Machine Screw 50pk

Product Description

The VALUE COLLECTION A98125 is a button head machine screw designed for general fastening applications in mechanical assemblies, enclosures, and equipment panels. It features an 8-32 Unified National Coarse (UNC) thread form with a 1/2-inch length measured under the head. The screw is driven by a Pin-In Torx bit, which provides tamper-resistance compared to standard Torx or Phillips drives. Constructed from 18-8 stainless steel with a bright, uncoated finish, it resists corrosion in mildly wet or chemically exposed environments. Licensed trades and assembly technicians install this fastener where a low-profile head and secure drive interface are required.

This screw is suited for light-duty mechanical and electrical assembly work, including mounting panels, brackets, covers, and components in HVAC equipment, electrical enclosures, and plumbing fixtures. The button head profile sits close to the mating surface, making it a common choice where clearance is limited. The 18-8 stainless steel material grade is appropriate for indoor and outdoor applications that require moderate corrosion resistance without requiring a coated or plated finish. This listing is sold in a package of 50 pieces, providing a practical quantity for service calls and shop stock.

Key Features

• Button head profile offers a low-profile, finished appearance with broad bearing surface
• Pin-In Torx drive adds tamper-resistance over standard open-socket drive types
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor-adjacent environments
• Bright uncoated finish — no plating that can flake, chip, or react with stainless hardware
• 8-32 UNC thread is a widely stocked, industry-standard size for equipment and panel fastening
• Packaged in quantities of 50 for shop stock or service van restocking

Compatibility

Designed as a standard 8-32 UNC inch-series machine screw for use in any tapped hole or threaded insert accepting an 8-32 thread with a 1/2-inch fastener length under the head.

Installation Notes

Installation requires a Pin-In Torx bit of the appropriate size — standard Torx bits will not seat correctly in a Pin-In Torx socket. Ensure the mating hole is tapped to the correct 8-32 UNC thread specification before driving the fastener. When fastening into electrical enclosures or equipment, de-energize all circuits before beginning work per applicable NEC guidelines. Do not exceed the material's shear rating by over-torquing; hand-tight plus a controlled fractional turn is appropriate for most light mechanical assemblies.
