Value Collection -63858-1 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION -63858-1 is a flat socket cap screw designed for fastening applications that require a flush or countersunk profile. The 82-degree flat head seats flush with the mating surface when installed in a properly countersunk hole, eliminating protrusion that could interfere with mating components or clearances. Driven by a 5/32-inch hex socket, the screw accepts a standard Allen wrench or hex bit driver. Manufactured from 18-8 stainless steel, it offers solid corrosion resistance for use in wet, outdoor, or chemically exposed environments. Thread size is 1/4-20 UNC with an overall length of 7/8 inches, and the shank is fully threaded to the head.

This flat socket cap screw is suited for light structural, mechanical, and equipment assembly applications where a countersunk fastener is required. Common use cases include panel mounting, machine guards, brackets, enclosures, and fixtures in HVAC, plumbing, electrical, and pool equipment installations. The 18-8 stainless construction makes it appropriate for both indoor and outdoor service where mild corrosion resistance is needed. This listing covers a package quantity of 100 pieces, appropriate for production assembly, maintenance stock, or service truck inventory.

Installation Notes

Installation is performed by general mechanics, maintenance technicians, or trade professionals using a 5/32-inch hex key or Allen-drive bit. The mating surface must be countersunk to 82 degrees at the correct diameter to allow the head to seat flush. Ensure the receiving thread is clean and undamaged before driving the fastener. Do not overtorque stainless fasteners, as 18-8 stainless is susceptible to galling; applying an anti-seize compound is recommended for threaded stainless assemblies.
