Value Collection 643281PR M14x1.5x40mm Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643281PR is a metric hex head cap screw designed for general-purpose mechanical fastening in assemblies requiring close thread tolerances. Sized M14 x 1.50 x 40 mm with full threading under the head, this screw meets DIN 961 and ISO 8676 standards for fine-pitch metric fasteners. The Grade 8.8 steel construction delivers a balance of tensile strength and ductility suited to medium-to-high-load applications. The bright uncoated finish leaves the steel in its natural state, making it appropriate for indoor assemblies, prototype work, or installations where a secondary coating will be applied. A 22 mm hex drive accommodates standard metric wrenches and sockets.

This fastener is used in industrial equipment, automotive sub-assemblies, machinery frames, and fabricated steel structures where a fine-pitch M14 thread is specified. The fine 1.50 mm pitch provides improved resistance to vibration loosening compared to coarse-thread equivalents. Maintenance technicians, millwrights, and fabricators working with metric hardware commonly stock this size for field repairs and production builds. The 40 mm length under the head suits moderate material stack-ups in bolted joints.

Key Features

• M14 x 1.50 fine-pitch thread per DIN 961 and ISO 8676 standards
• Grade 8.8 steel offers approximately 800 MPa minimum tensile strength class
• Fully threaded shank allows maximum thread engagement across a range of material thicknesses
• 22 mm hex drive fits standard metric wrenches and impact sockets
• Bright uncoated finish compatible with field-applied coatings or direct installation in protected environments
• Minimum order quantity of 25 pieces supports production and bulk maintenance use

Compatibility

Designed as a standard metric replacement or new-installation fastener for any bolted joint specifying an M14 x 1.50 fine-pitch hex head cap screw per DIN 961 or ISO 8676.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or qualified assemblers using a 22 mm metric wrench or socket. Verify that the mating threaded hole or nut matches the M14 x 1.50 fine-pitch specification before installation, as fine-pitch and coarse-pitch M14 fasteners are not interchangeable. Apply thread lubricant or anti-seize only when specified by the joint design, as it affects clamp load at a given torque. Consult the equipment manufacturer or a recognized fastener standard for proper torque values specific to the joint material and application.
