Value Collection A410417 Flat Socket Cap Screw M8x1.25 10pk

Product Description

The VALUE COLLECTION A410417 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Manufactured to DIN 7991 standards, it features a 90-degree flat head driven by a 5 mm hex socket. The M8x1.25 thread is partially threaded along a 40 mm overall length. The fastener is made from 316 austenitic stainless steel (Grade A4), providing strong resistance to corrosion and oxidation. This package contains 10 screws. It is suited for mechanical assemblies, fabrication work, and maintenance tasks where corrosion resistance and a low-profile head are required.

This screw is used in metric fastening applications across industrial, marine, food processing, and commercial environments where 316 stainless steel is specified for its corrosion resistance. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for structural joints and assemblies with multiple material layers. Installation is performed by licensed mechanics, millwrights, pipefitters, or experienced tradespeople using a 5 mm hex key or socket driver.

Key Features

• 90-degree flat head for flush or countersunk installation per DIN 7991
• M8x1.25 metric thread size with partial threading along the shank
• 5 mm hex socket drive for standard Allen key or socket wrench compatibility
• 316 austenitic stainless steel (Grade A4) for corrosion and chemical resistance
• 40 mm overall length suits medium-depth fastening applications
• Sold in a pack of 10 for stocking and service use

Compatibility

Designed as a DIN 7991 standard metric flat socket cap screw for use in any assembly specifying an M8x1.25 partially threaded countersunk hex socket fastener in 316 or Grade A4 stainless steel.

Installation Notes

Installation requires a 5 mm hex key or bit driver; confirm proper countersink angle of 90 degrees in the mating material before driving. Torque to the value specified by the assembly drawing or applicable mechanical standard for M8 Grade A4 fasteners. Do not mix stainless steel fasteners with incompatible metals in submerged or galvanic environments without appropriate isolation. De-energize and lock out any equipment before fastener removal or installation in live machinery.
