Value Collection 88547880 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 88547880 is a flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies. It features a hex socket drive accepting a 5/32-inch hex key and a flat, countersunk head profile that sits flush with or below the mating surface when fully seated. Manufactured from alloy steel with a black oxide finish, this screw offers improved corrosion resistance over bare steel and reduced light glare in finished assemblies. The 1/4-20 UNC thread with an overall length of 5/8 inches makes it a standard fastener for light-duty structural and mechanical joints.

This fastener is suited for general mechanical and structural applications where a low-profile, flush-mount fastening point is required. Common installation scenarios include machine frames, fixtures, jigs, panels, and enclosures across industrial, HVAC equipment housings, and electrical panel fabrication environments. The partial threading provides a smooth shank section for shear-load applications or precision-alignment holes. Installers working in trade environments will find this size frequently specified for equipment covers, brackets, and access panels.

Key Features

• Flat countersunk head profile seats flush with or below the surface for clean, low-profile assemblies
• 5/32-inch hex socket drive for standard hex key installation
• 1/4-20 UNC thread standard for broad hardware compatibility
• Alloy steel construction for strength in mechanical fastening applications
• Black oxide finish for moderate corrosion resistance and reduced surface reflectivity
• Partially threaded shank supports shear-load and alignment-critical holes

Compatibility

Designed as a standard 1/4-20 UNC flat socket cap screw for use in any application requiring a countersunk hex-socket fastener of this thread size and length.

Installation Notes

Installation is performed with a 5/32-inch hex key or Allen driver. Ensure the receiving hole is properly countersunk to the correct angle to achieve full head seating before torquing. Power down or de-energize any equipment before accessing fastener locations inside electrical or HVAC enclosures. Follow applicable equipment manufacturer specifications for fastener torque requirements, as no torque value is specified for this part.
