Value Collection A410387 M5x0.8 Flat Socket Cap Screw 25 Pack

Product Description

The VALUE COLLECTION A410387 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Featuring a 90-degree flat head with a 3.00 mm hex socket drive, this screw is fully threaded along its 8.00 mm overall length with an M5x0.8 thread size. It is manufactured from 316 austenitic stainless steel, Grade A4, offering strong resistance to corrosion in wet, chemical, or marine environments. This screw meets DIN 7991 standards and is suited for use by mechanical contractors, millwrights, plumbers, and maintenance technicians working with stainless fastener assemblies.

This flat socket cap screw is used in applications where a low-profile, countersunk head is required and the fastener must not protrude above the surface. Common install scenarios include equipment panels, pump housings, valve bodies, and enclosures in commercial and industrial settings. The 316 stainless steel construction makes it particularly well suited for corrosive or high-moisture environments such as pool equipment, marine fixtures, and chemical processing assemblies. Sold in packs of 25, it is appropriate for both single-repair and small-batch production use.

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M5x0.8 threaded applications in stainless steel fastener assemblies across industrial, commercial, and marine environments.

Installation Notes

Installation requires a 3.00 mm hex key or Allen driver rated for the applied torque. Ensure the mating hole is properly countersunk to 90 degrees to achieve full seating of the flat head. Power down or de-energize any equipment before fastener service. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or high-conductivity environments to reduce galvanic corrosion risk.
