Value Collection -42758-1 M8x1.25 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42758-1 is a partially threaded hex socket cap screw in M8 x 1.25 metric thread with a 75 mm length under head. Manufactured from alloy steel with a grade 12.9 rating, this fastener delivers high tensile strength suited to demanding mechanical and structural applications. The black oxide finish provides mild corrosion resistance and reduces light reflection on the fastener surface. Installed with a hex (Allen) key drive, it seats flush for clean, low-profile clamping force. Trade professionals, maintenance technicians, and mechanical contractors rely on this grade for high-stress bolted joints where fastener integrity is critical.

This screw is suited for general industrial assembly, machinery maintenance, tooling fixtures, and structural bolted connections that require a high-strength metric cap screw. The M8 x 1.25 thread pitch and 75 mm under-head length make it appropriate for medium-to-heavy panel and component fastening. It conforms to DIN 912 and ISO 898-1 fastener standards, making it a direct fit wherever those specifications are called out. Minimum order quantity is 50 pieces per order.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• M8 x 1.25 metric thread, partially threaded shank
• 75 mm length under head for medium-to-deep material engagement
• Hex socket (Allen key) drive for positive torque transfer in tight spaces
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a DIN 912 and ISO 898-1 compliant M8 x 1.25 metric hex socket cap screw suitable for industrial machinery, fixtures, and structural assemblies specifying grade 12.9 alloy steel fasteners.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians using a calibrated torque wrench and the appropriate metric hex key or bit. Always de-energize and lock out equipment before fastener service on live machinery. Grade 12.9 fasteners should not be substituted with lower-grade hardware; confirm the joint design calls for 12.9 before installation. Follow applicable industry torque guidelines for M8 grade 12.9 fasteners as specified by the equipment manufacturer or engineering documentation.
