Value Collection A410399 M6x1 Flat Socket Cap Screw 25 Pack

Product Description

The VALUE COLLECTION A410399 is an M6x1 flat socket cap screw manufactured from 316 austenitic stainless steel to Grade A4 specification. The 90-degree flat head accepts a 4 mm hex socket drive and is fully threaded along its 12 mm overall length. This fastener meets DIN 7991 standard and is suited for flush or countersunk installations where corrosion resistance is a primary requirement. Licensed tradespeople and industrial maintenance technicians install these screws in applications where the fastener head must sit flush or below the mating surface. Each package contains 25 pieces.

This screw is commonly used in plumbing, marine, chemical processing, and food-service equipment environments where 316 stainless steel is specified for superior resistance to chlorides and oxidizing agents. The fully threaded M6x1 metric profile makes it a straightforward replacement or maintenance fastener in assemblies originally designed to DIN 7991 or equivalent countersunk hex socket standards. The metric thread standard ensures compatibility with standard M6 metric tapped holes.

Compatibility

Designed as a DIN 7991 compliant flat socket cap screw for use in any application requiring an M6x1 fully threaded countersunk hex socket fastener in stainless steel.

Installation Notes

Installation should be performed by qualified maintenance or trade personnel using a 4 mm hex key or appropriate hex socket bit. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Avoid over-torquing stainless steel fasteners, as galling is a risk; applying an anti-seize compound compatible with stainless steel is a common field practice. Power down or depressurize any equipment being serviced before replacing fasteners in live assemblies.
