Value Collection A410389 M5x0.8 Flat Socket Cap Screw 25 Pack

Product Description

The VALUE COLLECTION A410389 is a metric flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies, industrial equipment, and structural connections. Manufactured from 316 austenitic stainless steel to Grade A4, this fastener delivers strong corrosion resistance in wet, marine, and chemical environments. The M5x0.8 thread size pairs with a 90-degree flat head and a 3.00 mm hex socket drive. The screw is fully threaded along its 12.00 mm overall length, making it well suited for through-hole applications where full thread engagement is required. Each package contains 25 pieces. This fastener is installed by maintenance technicians, millwrights, pipefitters, and mechanical contractors.

This flat socket cap screw is used wherever a flush or low-profile fastener head is needed and corrosion resistance is a priority. Typical applications include stainless steel fabrications, food-processing equipment, marine hardware, plumbing fixtures, pool equipment enclosures, and HVAC component assemblies. The fully threaded shank suits thin-material and close-tolerance installations. The hex socket drive allows torquing in confined spaces where a conventional wrench cannot reach.

Designed as an OEM-style or aftermarket replacement flat socket cap screw for metric M5x0.8 countersunk hex socket applications conforming to DIN 7991.

Installation Notes

Installation is performed with a 3.00 mm hex key or metric hex bit driver. Always verify that the mating countersink angle matches the 90-degree head geometry before torquing. Ensure the receiving hole is clean and free of debris before fastener insertion. For installations in corrosive or submerged environments, apply a compatible anti-seize compound appropriate for stainless steel to prevent galling during installation and future removal.
