Value Collection A996738 M8x1.25 Hex Socket Cap Screw 140mm

Product Description

The VALUE COLLECTION A996738 is a metric hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and trade assembly work. This screw features an M8 x 1.25 thread size and a 140 mm length under head, with partial threading along the shank. It is manufactured from alloy steel with a black oxide coating, achieving a material grade of 12.9 — the highest standard strength class for metric fasteners. The hex socket drive accepts a standard hex key or Allen-type driver. This fastener is appropriate for use by mechanical contractors, millwrights, equipment technicians, and general trade professionals requiring a high-tensile metric cap screw.

This screw is suited for machinery assembly, equipment mounting, structural fastening, and general mechanical applications where a high-strength metric fastener with a low-profile socket cap head is required. The partial threading design provides a smooth shank section, which is useful in applications requiring precise hole alignment or where the screw passes through a clearance hole before threading into a tapped bore. Sold in a package quantity of 10 pieces.

Key Features

• M8 x 1.25 thread size with 140 mm length under head
• Material grade 12.9 alloy steel for high tensile and yield strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Partially threaded shank for clearance-hole and alignment applications
• Hex socket drive compatible with standard hex keys and socket drivers
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw compatible with M8 x 1.25 tapped holes in machinery, equipment frames, and structural assemblies requiring a grade 12.9 fastener.

Installation Notes

Installation is performed using a properly sized hex key or hex socket driver matched to the M8 socket cap head. Ensure the receiving hole is tapped to M8 x 1.25 and that thread engagement depth meets the requirements of the application load. Apply appropriate thread-locking compound or torque specifications per the equipment manufacturer guidelines. Inspect threads and mating surfaces for damage or contamination before installation.
