Value Collection 88547898 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 88547898 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 5/32-inch hex socket drive and is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection. The 1/4-20 UNC thread and 3/4-inch overall length make it a common size for machine assembly, tooling fixtures, and mechanical subassemblies. Installation requires a 5/32-inch hex key or Allen driver. This screw is partially threaded along its shank length.

Flat socket cap screws are used across a wide range of industrial and mechanical applications where a low-profile, flush-seating fastener is required. Typical install scenarios include machine frames, brackets, jigs, fixtures, and enclosures where protruding fastener heads would interfere with mating surfaces or moving parts. The black oxide finish suits indoor or lightly controlled environments. This part is sold in a package quantity of 13 and is appropriate for use by machinists, maintenance technicians, millwrights, and mechanical assemblers working in inch-measurement systems.

Key Features

• Flat head profile seats flush in countersunk holes, eliminating protrusion above the work surface
• 5/32-inch hex socket drive for precise torque application with standard Allen keys or hex drivers
• Alloy steel construction provides higher tensile strength compared to standard carbon steel fasteners
• Black oxide finish offers mild corrosion resistance and a non-reflective appearance
• 1/4-20 UNC thread is a widely stocked, industry-standard inch-series coarse thread
• Partially threaded shank allows controlled clamping force on mating components

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 1/4-20 UNC countersunk socket fastener with a 3/4-inch overall length.

Installation Notes

Installation requires a 5/32-inch hex key or Allen driver rated for the applied torque. Ensure the mating hole is properly countersunk to the correct angle to fully seat the flat head flush with the surface. Alloy steel fasteners should not be installed in direct contact with dissimilar metals in wet environments without appropriate isolation to prevent galvanic corrosion. Always verify thread engagement depth meets applicable engineering standards for the joint design.
