Value Collection R88444642 Button Head Machine Screw

Product Description

The VALUE COLLECTION R88444642 is a 10-24 x 1/2 inch button head machine screw manufactured from 18-8 stainless steel with a bright uncoated finish. The pin-in hex socket drive requires a pin-in hex key for installation, which provides tamper resistance in accessible or semi-public installations. The length measurement is taken under the head. This fastener is threaded to the Unified National Coarse (UNC) standard and is suited for light-duty mechanical assemblies, panel work, and equipment fabrication across HVAC, electrical, and general trade applications. Installation is performed by qualified tradespeople using the appropriate pin-in hex key tool.

This screw is a standard inch-series fastener intended for use in threaded holes or with mating nuts where a low-profile button head and tamper-resistant drive are specified. It is commonly used in sheet metal assemblies, equipment enclosures, access panels, and control boxes across residential and commercial mechanical systems. The 18-8 stainless steel construction provides corrosion resistance suitable for indoor and moderately exposed environments.

Key Features

• Button head profile provides a low-profile, finished appearance in visible assemblies
• Pin-in hex socket drive adds tamper resistance compared to standard hex socket fasteners
• 18-8 stainless steel construction offers corrosion resistance for general mechanical use
• Bright uncoated finish maintains base material properties without added plating
• UNC thread standard ensures broad compatibility with inch-series tapped holes and nuts
• Length measured under head for consistent installation depth reference

Compatibility

Designed as a standard 10-24 UNC inch-series machine screw for use in threaded holes, tapped components, or with matching 10-24 hex nuts across general mechanical and trade assemblies.

Installation Notes

Installation requires a pin-in hex key sized for the socket drive. Ensure mating threads are clean and properly tapped to 10-24 UNC before driving the fastener. Do not use a standard hex key, as it will not engage the center pin and may damage the drive recess. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the assembly being serviced.
