Value Collection R88444808 Button Head Screw 8-32 X 1/2 in

Product Description

The VALUE COLLECTION R88444808 is an 8-32 x 1/2 inch button head machine screw manufactured from 18-8 stainless steel with a bright uncoated finish. The button head profile sits low and wide, distributing clamp load across a broader bearing surface compared to pan or round head styles. The Pin-In Hex Socket drive requires a pin-in hex key, providing tamper-resistance in applications where fastener access should be restricted. This fastener follows Unified National Coarse (UNC) thread standards and is sized with length measured under the head. Minimum order quantity is 100 pieces per order. This fastener is suited for mechanical assembly, HVAC enclosures, electrical panels, and light structural applications where corrosion resistance is a priority.

The 18-8 stainless steel construction makes this screw appropriate for indoor and moderately corrosive outdoor environments where carbon steel fasteners would oxidize. Common install scenarios include fastening sheet metal covers, control board brackets, terminal enclosures, and equipment panels in HVAC, plumbing, and electrical applications. The 8-32 UNC thread is a standard machine screw size found widely in trade equipment and light industrial assemblies. Technicians and assemblers across multiple trades use this size for general-purpose fastening into threaded holes or with matching nuts.

Key Features

• Button head profile provides low-profile, wide-bearing-surface clamping
• Pin-In Hex Socket drive adds tamper-resistance versus standard hex socket
• 18-8 stainless steel offers good corrosion resistance without coating
• 8-32 UNC thread is a widely standardized machine screw size
• Length measured under head — 1/2 inch thread engagement depth
• Bright uncoated finish — no plating to chip or delaminate

Compatibility

Designed as an OEM-style replacement or stock fastener for any assembly using 8-32 UNC threaded holes or matching hex nuts requiring a button head profile with a tamper-resistant Pin-In Hex Socket drive.

Installation Notes

Install using a pin-in hex key sized for the socket drive to avoid cam-out and fastener damage. Ensure the mating hole is threaded to 8-32 UNC specification or use a matching nut before driving the screw. Power down and de-energize any electrical or HVAC equipment before accessing fastened enclosures or panels. Do not overtighten stainless steel fasteners into stainless threaded holes without anti-seize compound, as galling can occur.
