Value Collection 532126P M8x1.25 Hex Socket Cap Screw 55mm

Product Description

The VALUE COLLECTION 532126P is an M8 x 1.25 metric hex socket cap screw intended for precision fastening applications across industrial, mechanical, and structural assemblies. The screw measures 55 millimeters under the head and is partially threaded, which helps maintain clamping force in through-bolt applications. It is manufactured from alloy steel to a grade 12.9 strength rating, making it suitable for high-load and high-stress joints. A black oxide finish provides moderate corrosion resistance and reduces light reflection in service environments. This fastener is installed by machinists, millwrights, mechanical contractors, and maintenance technicians using a standard hex key or Allen driver.

This cap screw is used in general industrial and OEM manufacturing settings where a recessed hex drive is required for flush or countersunk installation. The M8 x 1.25 thread pitch is common in metric machine assemblies, including equipment frames, jigs, fixtures, and mechanical subassemblies. The partial threading is particularly effective when fastening through clearance holes where the unthreaded shank must resist shear loads. This item is sold individually but requires a minimum order quantity of 100 units per order.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• M8 x 1.25 metric thread, partially threaded with 55 millimeters length under head
• Hex socket drive accepts standard hex key or Allen driver
• Black oxide finish for moderate corrosion resistance and low-glare appearance
• Meets DIN 912 and ISO 898-1 fastener standards
• Minimum order quantity of 100 units per order

Compatibility

Designed as a direct-fit metric fastener for applications requiring an M8 x 1.25 thread pitch and DIN 912 hex socket cap screw geometry. Suitable for metric machine assemblies, OEM equipment, and maintenance replacement where grade 12.9 alloy steel is specified.

Installation Notes

Installation is performed using a correctly sized hex key or socket drive tool; using an undersized or worn key risks rounding the socket drive and should be avoided. Verify thread engagement depth and hole clearance before torquing, and never exceed the torque specification called out in the equipment service documentation for grade 12.9 M8 fasteners. De-energize and lock out any machinery before accessing fastener locations on live equipment. Inspect threads and mating surfaces for damage or contamination prior to assembly.
