Value Collection -42729-1 M5x0.80 Hex Socket Cap Screw 55mm

Product Description

The VALUE COLLECTION -42729-1 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and maintenance settings. Sized M5 x 0.80 mm with a 55 mm length under head, this screw is partially threaded and features a hex drive socket for use with a standard hex key or Allen wrench. Manufactured from alloy steel to material grade 12.9, it delivers high tensile and proof load capacity. A black oxide coating provides moderate corrosion resistance and reduces light reflection on finished assemblies. Installation is handled by maintenance technicians, machinists, and mechanical assembly professionals.

This fastener is suited for precision mechanical assemblies, machine frames, fixtures, and equipment where a recessed drive and a low-profile cap head are required. The M5 x 0.80 mm thread is a standard metric coarse pitch, making it compatible with a wide range of tapped holes in steel, aluminum, and cast components. Partial threading allows the unthreaded shank to bear shear loads, which is useful in dowel-fit and shoulder applications. Sold in a minimum order quantity of 50 pieces per order.

Compatibility

Designed as an OEM-style replacement or stock fastener for metric M5 x 0.80 mm tapped hole applications in mechanical assemblies, fixtures, and industrial equipment.

Installation Notes

Install using a correctly sized metric hex key or socket bit to avoid stripping the drive recess. Ensure mating threads are clean and free of debris before installation. Grade 12.9 fasteners should not be substituted with lower-grade hardware in high-load or safety-critical joints. Follow applicable industry torque guidelines for M5 grade 12.9 fasteners as specified in your assembly documentation.
