Value Collection 643563PR M5 Hex Head Cap Screw 8.8

Product Description

The VALUE COLLECTION 643563PR is a metric hex head cap screw designed for general mechanical assembly where a fully threaded fastener is required. Built to Grade 8.8 steel with a bright uncoated finish, this screw meets DIN 933 and ISO 4017 standards, making it a reliable choice for structural and non-structural bolted connections. The M5 x 0.80 thread pitch and 45 mm length under head suit a wide range of machine frames, brackets, and equipment panels. Sold individually per package, with a minimum order quantity of 100 pieces. Installation requires an 8 mm hex wrench or socket driver.

This fastener is suited for use in manufacturing, maintenance, and fabrication environments where metric hardware is specified. It is commonly installed by millwrights, maintenance technicians, equipment assemblers, and field service personnel working on mechanical systems, enclosures, and structural sub-assemblies that call for a standard DIN 933 or ISO 4017 compliant hex cap screw.

Installation Notes

Installation is performed by hand-threading into a properly tapped or through-hole metric M5 x 0.80 boss, then torquing with an 8 mm wrench or socket driver. Always confirm the mating thread is clean and free of debris before installation. Do not apply fasteners beyond their rated grade in applications requiring higher strength classifications. Follow applicable equipment manufacturer specifications for torque values.
