The VALUE COLLECTION 643379PR is a metric hex head cap screw engineered for fastening applications that demand precision threading and reliable clamping force. Sized M8 x 1.00 with a 50 mm length under head, this fully threaded fastener is manufactured from Grade 8.8 steel, indicating a tensile strength appropriate for medium- to high-load mechanical assemblies. The uncoated bright finish leaves the steel surface clean and ready for use or post-installation coating. A 13 mm hex drive head allows standard wrench engagement. Mechanical contractors, millwrights, equipment assemblers, and maintenance technicians working with metric hardware will find this screw suited to a wide range of structural and equipment fastening tasks.
This fastener is intended for metric-thread applications in industrial, commercial, and mechanical service environments. It conforms to DIN 961 and ISO 8676 standards, making it appropriate for equipment assemblies, machinery mounting, brackets, and structural connections where a fine-pitch M8 metric thread is specified. The fully threaded design maximizes thread engagement across the full grip length, which is particularly useful in through-hole applications and thinner material stacks. Sold individually, this screw is ordered in multiples of 100 units minimum.
Designed for use in any application requiring a fully threaded M8 x 1.00 metric hex head cap screw conforming to DIN 961 and ISO 8676 standards.
Installation should be performed by a qualified mechanic or technician familiar with metric fastener torque requirements for Grade 8.8 hardware. Always ensure the mating thread is clean and free of debris before installation. De-energize or lock out any equipment being serviced before fastener replacement or assembly work. Do not mix metric and unified thread fasteners in the same assembly.
