Value Collection 36817 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 36817 is a flat socket cap screw designed for flush or countersunk fastening applications in metalworking, fabrication, and mechanical assembly. It features an 82-degree flat head profile and a 5/32-inch hex socket drive, allowing recessed installation where a low-profile or flush surface is required. The fastener is manufactured from alloy steel with a black oxide finish, providing moderate corrosion resistance and a consistent dark appearance. The 1/4-20 UNC thread runs the full 1-1/2-inch length of the fastener. Licensed trades and skilled fabricators working on machine assemblies, fixtures, and structural components install this type of screw routinely.

This screw is suited for residential and commercial mechanical assemblies, fixture fabrication, jigs, and general industrial applications where a countersunk fastening point is required. The fully threaded 1-1/2-inch body provides maximum thread engagement across the full shank length. The black oxide finish is appropriate for interior or dry-environment applications. Meets ASME/ANSI B18.3 and ASTM F835 fastener standards. Sold individually with a minimum order quantity of 25 pieces.

Key Features

• 82-degree flat head profile for flush or countersunk installations
• 5/32-inch hex socket drive for use with standard Allen keys or hex drivers
• Fully threaded 1/4-20 UNC body over the full 1-1/2-inch length
• Alloy steel construction with black oxide finish for a durable, low-reflectance surface
• Meets ASME/ANSI B18.3 and ASTM F835 standards

Compatibility

Designed as an OEM-style replacement or general-use flat socket cap screw for any application requiring a 1/4-20 UNC, 1-1/2-inch fully threaded countersunk fastener with an 82-degree flat head and hex socket drive.

Installation Notes

Install using a 5/32-inch hex key or Allen driver; ensure the receiving hole is properly countersunk to 82 degrees to allow full head seating. Verify thread engagement depth before final torque to avoid stripping the alloy steel threads. Black oxide finish offers limited corrosion protection and is best suited for dry or lightly oiled environments. Follow applicable mechanical and structural assembly codes for your jurisdiction when specifying fastener grade and torque requirements.
