Value Collection 644006PR M5 X 0.80 X 35 Mm Hex Cap Screw

Product Description

The VALUE COLLECTION 644006PR is a metric hex head cap screw designed for general mechanical fastening applications. It features an M5 x 0.80 thread profile and a 35 mm length under the head with partial threading along the shank. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener meets DIN 931 and ISO 4014 standards. The 8 mm hex drive size suits standard metric wrenches and sockets. Grade 8.8 designates a medium-carbon steel fastener with a minimum tensile strength suitable for structural and mechanical assemblies. Licensed trades and maintenance professionals use this screw where a metric partially threaded fastener is required.

This fastener is suited for residential and commercial mechanical assemblies, equipment maintenance, and fabrication work where metric hardware conforming to DIN 931 or ISO 4014 is specified. Partial threading along the shank allows the unthreaded portion to serve as a shoulder or locating feature in precision joint applications. It is commonly used in HVAC equipment panels, pump housings, electrical enclosures, and other light-to-medium duty mechanical assemblies that call for a standard M5 hex cap screw.

Compatibility

Designed as a standard metric hex head cap screw for use in any application requiring an M5 x 0.80 partially threaded fastener conforming to DIN 931 or ISO 4014 specifications.

Installation Notes

Installation should be performed by a qualified technician or mechanic using a calibrated metric wrench or socket set. Always power down or de-energize equipment before servicing fasteners on electrical or mechanical assemblies. Do not exceed the rated load capacity of Grade 8.8 fasteners by substituting them in applications specified for higher-grade hardware. Ensure mating threads are clean and free of debris before installation to prevent galling or cross-threading.
