Value Collection 643279PR Hex Head Cap Screw M14x1.5x30mm

Product Description

The VALUE COLLECTION 643279PR is a metric hex head cap screw designed for fastening applications requiring a fine-pitch thread profile. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fully threaded fastener measures M14 x 1.50 mm thread size with a 30 mm length under head and a 22 mm hex drive. Grade 8.8 denotes a medium-high strength carbon steel with a minimum tensile strength suitable for structural and mechanical assemblies. It conforms to DIN 961 and ISO 8676 standards, making it a reliable choice for metric-specified engineering work across a range of industries.

This cap screw is used in metric fastening applications where a fine-pitch thread is specified over a standard coarse pitch — common in automotive, machinery, hydraulic equipment, and precision mechanical assemblies. The fully threaded shank provides maximum thread engagement across the full 30 mm length, making it well suited for thinner flanges, adjustable clamping, and applications where the fastener threads into a tapped hole rather than clamping with a nut. Machinists, millwrights, and mechanical technicians are the typical installers.

Key Features

• M14 x 1.50 mm fine-pitch thread for applications where coarse thread is not specified
• Fully threaded shank along the 30 mm length under head for maximum thread engagement
• Grade 8.8 steel construction provides reliable medium-high tensile strength
• 22 mm hex drive compatible with standard metric wrenches and sockets
• Bright, uncoated finish — no additional coating to affect dimensional tolerances
• Conforms to DIN 961 and ISO 8676 standards for metric fine-pitch hex cap screws

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 961 and ISO 8676, suitable for use in any tapped or through-hole application specifying an M14 x 1.50 mm fine-pitch fastener.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical technicians using a standard 22 mm metric wrench or socket. Always verify that the mating thread is M14 x 1.50 mm fine pitch before installation — mixing fine and coarse pitch threads damages both the fastener and the tapped hole. Apply appropriate thread lubricant or thread-locking compound per the assembly specification before torquing. Follow the equipment manufacturer torque specification for Grade 8.8 fasteners of this diameter.
