Value Collection 88547872 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 88547872 is a flat socket cap screw designed for fastening applications where a flush or countersunk head profile is required. Manufactured from alloy steel with a black oxide finish, this screw offers good corrosion resistance and a clean, low-profile appearance when seated. The 1/4-20 UNC thread and 1/2 inch overall length make it a commonly specified size across mechanical assembly, fixturing, and equipment fabrication. Drive engagement is via a 5/32 inch hex socket, requiring a hex key or Allen driver for installation. The partial thread length is suited to applications where thread engagement in a blind or through-tapped hole is controlled.

This flat socket cap screw is used in light to medium-duty fastening tasks across a range of industries, including HVAC equipment assembly, electrical enclosure fabrication, pump and motor mounting, and general mechanical maintenance. Its countersunk flat head seats flush with or below the surface of the mating material, making it suitable for close-tolerance assemblies where protruding fastener heads are not acceptable. It is sold in a package quantity of 13.

Key Features

• Flat head profile allows flush or countersunk seating in mating surfaces
• 5/32 inch hex socket drive for precise torque application with standard Allen keys
• Alloy steel construction provides strength suitable for mechanical fastening applications
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Partial threading supports controlled engagement in tapped blind holes or through-hole assemblies
• 1/4-20 UNC thread standard for broad compatibility with tapped holes and hardware

Compatibility

Designed for use in any application requiring a 1/4-20 UNC partially threaded flat socket cap screw with a 5/32 inch hex socket drive and 1/2 inch overall length.

Installation Notes

Install using a correctly sized 5/32 inch hex key or Allen driver to avoid rounding the socket. Ensure the mating hole is properly countersunk to the correct angle to allow the flat head to seat fully flush. De-energize and lock out any equipment before accessing fastener locations on powered assemblies. Do not overtighten; follow the torque specification for the mating material and thread class per applicable mechanical or equipment standards.
