Value Collection 532122P M8x1.25 Hex Socket Cap Screw 45mm

Product Description

The VALUE COLLECTION 532122P is a metric hex socket cap screw designed for high-strength fastening applications. Built to M8 x 1.25 thread specification with a 45mm length under head, this screw is partially threaded and manufactured from alloy steel with a black oxide finish. It conforms to DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, indicating very high tensile strength suitable for demanding mechanical assemblies. Machinists, millwrights, and maintenance technicians use this type of fastener where a flush or low-profile socket drive is required and structural integrity is critical.

This screw is commonly used in industrial equipment assembly, machine frames, tooling fixtures, and general mechanical fabrication. The M8 x 1.25 metric coarse thread is one of the most widely used thread forms in equipment manufactured to metric standards. The partially threaded shank provides a smooth bearing surface between clamped components, which is beneficial in joints subject to shear loading. This item is sold in a minimum order quantity of 100 pieces per order.

Key Features

• M8 x 1.25 metric coarse thread with 45mm length under head
• Partially threaded shank for improved shear resistance in clamped joints
• Alloy steel construction with 12.9 material grade for very high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces surface glare
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Hex socket (internal hex) drive for high torque application with standard Allen or socket tooling

Compatibility

Designed as an OEM-style and general-purpose replacement or supply fastener for metric M8 x 1.25 threaded applications conforming to DIN 912 socket head cap screw dimensional standards.

Installation Notes

Installation should be performed by qualified mechanics or maintenance personnel using calibrated torque tooling appropriate for grade 12.9 fasteners. Always clean and inspect mating threads before installation to prevent galling or cross-threading. Hex socket drive requires a properly sized Allen key or hex bit socket; using an undersized or worn key risks rounding the socket. Do not substitute lower-grade fasteners in joints originally specified for 12.9-grade hardware.
