Value Collection A410049 Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION A410049 is a metric hex head cap screw designed for general-purpose fastening applications where corrosion resistance is required. Manufactured from Grade 316 austenitic stainless steel (Metric Grade A4), this fully threaded screw meets DIN 933 standards and is suitable for use in wet, marine, and chemically exposed environments. The M8 x 1.25 thread pitch and 25 mm length under head make it a commonly specified size for machinery, equipment assemblies, and structural connections. A licensed mechanic, millwright, or maintenance technician typically installs this fastener using a 13 mm hex wrench or socket.

This screw is used in residential, commercial, and industrial applications where a metric fastener with high corrosion resistance is specified. It is well suited for marine hardware, food processing equipment, chemical processing environments, and outdoor structural assemblies. The fully threaded shank engages the full clamped length, making it appropriate for through-bolt configurations and short-grip connections where maximum thread engagement is needed. Sold in multiples of 25.

Installation Notes

Installation requires a 13 mm socket, wrench, or hex driver. Always verify thread engagement depth and mating material compatibility before installation, particularly when joining dissimilar metals, as galvanic corrosion risk should be evaluated. Torque to the value specified by the equipment manufacturer or applicable mechanical standard for M8 Grade A4 stainless fasteners. Do not use impact drivers at full power on stainless steel fasteners, as galling of the threads can occur.
