Value Collection 532120P M8x1.25 Hex Socket Cap Screw 40mm

Product Description

The VALUE COLLECTION 532120P is an M8 x 1.25 hex socket cap screw designed for high-strength mechanical fastening in industrial and commercial applications. This screw measures 40 mm in length under the head and is partially threaded, providing a strong grip in precision-fit assemblies. Manufactured from alloy steel to material grade 12.9, it carries one of the highest tensile strength ratings available for metric fasteners. A black oxide finish provides mild corrosion resistance and reduces surface reflectivity. This fastener conforms to DIN 912 and ISO 898-1 standards and is installed using a hex (Allen) drive tool. Mechanical technicians, machinists, and maintenance professionals are the typical installers.

This screw is suited for heavy-duty bolted connections in machine frames, hydraulic components, tooling fixtures, and structural assemblies where high clamping force is required. The partial threading allows for precise shank-to-bore alignment in close-tolerance bores, making it a common choice in precision machining and equipment manufacturing. Grade 12.9 alloy steel is specified where standard hardware-grade fasteners would be insufficient under dynamic or high-load conditions. This SKU ships in a package quantity of 1, with a minimum order quantity of 100 units.

Key Features

• M8 x 1.25 thread size with 40 mm length under head
• Grade 12.9 alloy steel construction for maximum tensile strength
• Partially threaded shank for precise bore alignment in close-tolerance applications
• Black oxide finish for mild corrosion resistance and low reflectivity
• Hex socket (Allen) drive for high-torque installation in confined spaces
• Conforms to 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 threaded bores in machinery, fixtures, and structural components requiring grade 12.9 fastener performance.

Installation Notes

Install using a properly sized hex key or socket drive rated for grade 12.9 fasteners. Always verify that the mating threaded bore meets the same metric pitch specification before installation. Follow applicable torque values from published grade 12.9 fastener torque charts for M8 fasteners, as this product does not ship with torque documentation. Grade 12.9 fasteners are not intended for use with soft or low-grade threaded inserts.
