Value Collection 532117PR Hex Socket Cap Screw M8x1.25

Product Description

The VALUE COLLECTION 532117PR is an M8 x 1.25 metric hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Manufactured from alloy steel and finished with a black oxide coating, this screw delivers a material grade of 12.9 — the highest standard class for metric fasteners — providing exceptional tensile and proof load strength. With an 18 mm length under head and full threading along the shank, it seats flush and locks securely into tapped holes without requiring a nut. Licensed trades and machine technicians rely on this screw type for precision assemblies where torque retention and compact head profile are critical.

This fastener is suited for use in industrial machinery, hydraulic equipment, automotive components, tooling fixtures, and structural brackets requiring metric fasteners with a recessed drive profile. The hex socket drive accepts a standard Allen key or hex bit driver, making it practical in confined spaces where a wrench cannot reach. It conforms to DIN 912 and ISO 898-1 standards, making it interchangeable in metric-spec assemblies that call for those fastener standards. Sold individually with a minimum order quantity of 100 units per order.

Key Features

• Material grade 12.9 alloy steel for maximum tensile and proof load strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Fully threaded shank for consistent clamping force in through-hole and tapped applications
• Hex socket (Allen) drive allows installation in tight clearance areas
• Conforms to DIN 912 and ISO 898-1 fastener standards
• 18 mm length under head suits a range of medium-thickness workpiece stacks

Compatibility

Designed as an OEM-style and aftermarket replacement metric cap screw for any assembly specifying an M8 x 1.25 pitch fully threaded hex socket fastener per DIN 912 or ISO 898-1.

Installation Notes

Installation requires an appropriately sized metric hex key or Allen bit driver; always verify the correct key size before applying torque to avoid cam-out damage. Power down or de-energize any equipment before servicing fastened assemblies per applicable safety lockout-tagout procedures. Do not mix metric and imperial fasteners in the same threaded hole. Follow the equipment manufacturer torque specifications for M8 grade 12.9 fasteners when tightening into tapped bores.
