Value Collection A410390 M5x0.8 Flat Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION A410390 is a metric flat socket cap screw manufactured from 316 austenitic stainless steel to Grade A4 specification. The 90-degree flat head seats flush with or below the surface of the mating material, making it well suited for applications where a low-profile or countersunk fastener is required. Drive engagement is through a 3.00 mm hex socket. The screw is fully threaded along its 16.00 mm overall length with an M5x0.8 thread pitch and conforms to DIN 7991 dimensional standards. This package contains 25 pieces. Maintenance technicians, millwrights, and industrial service professionals install this type of fastener across a wide range of equipment and structural assemblies.

This fastener is appropriate for metric applications in corrosive or wet environments where stainless steel is specified over carbon steel. The 316 alloy provides elevated resistance to chlorides and chemical exposure, making it a common choice in marine, food-service, pool, and chemical-processing environments. The DIN 7991 standard ensures dimensional interchangeability with other compliant metric flat socket cap screws of the same thread size and length.

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw for use in M5x0.8 tapped holes requiring a countersunk, hex-socket-drive fastener.

Installation Notes

Installation requires a 3.00 mm hex key or compatible hex socket bit. Ensure the mating hole is properly countersunk to the correct 90-degree included angle before installation to achieve full head seating. De-energize, depressurize, or lock out the equipment being serviced before fastener replacement as required by applicable site safety procedures. Avoid mixing dissimilar metals where galvanic corrosion is a concern.
