Value Collection 815421PR M14x2 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 815421PR is a metric hex head cap screw designed for structural and mechanical fastening applications where precise thread engagement and corrosion resistance are required. Sized at M14 x 2.00 with a 55 mm length under head, this partially threaded fastener is manufactured from Grade 8.8 steel and finished with a zinc plating for moderate corrosion protection. The 22 mm hex drive size accommodates standard metric wrenches and sockets. It conforms to DIN 931 and ISO 4014 dimensional standards, making it a reliable choice for engineers, maintenance technicians, and assembly professionals working in metric-spec environments.

This fastener is suited for general industrial, mechanical, and structural assembly applications where metric hardware is specified. Partially threaded shanks are commonly used where a smooth unthreaded grip length is needed to clamp mating parts without thread engagement through the full joint. Typical applications include machinery assembly, frame fabrication, equipment mounting, and maintenance repair operations requiring an M14 coarse-thread bolt.

Key Features

• M14 x 2.00 thread size with 55 mm length under head for substantial grip and clamping depth
• Grade 8.8 steel construction provides high tensile strength suitable for structural fastening
• Zinc-plated finish offers moderate protection against corrosion in general-use environments
• Partially threaded shank per DIN 931 and ISO 4014 for proper clamp load distribution
• 22 mm hex size compatible with standard metric wrenches and impact sockets
• Metric thread standard ensures dimensional conformance for international and OEM applications

Compatibility

Designed as a standard metric replacement or new-installation hex head cap screw for any application specifying an M14 x 2.00 x 55 mm partially threaded fastener per DIN 931 or ISO 4014.

Installation Notes

Installation is performed by general maintenance technicians and assembly professionals using a 22 mm open-end wrench, box wrench, or metric socket. Ensure mating threads are clean and free of debris before installation. Always verify that the fastener grade and thread pitch match the application specification before torquing. Follow the equipment manufacturer's torque specifications for M14 Grade 8.8 hardware, as no torque value is provided with this listing.
