The VALUE COLLECTION 643511PR is a fully threaded hex head cap screw designed for metric fastening applications in mechanical assembly, equipment fabrication, and structural connections. It carries an M8 x 1.25 thread profile with a 110 mm length under head and is manufactured from Grade 8.8 steel, indicating a medium-high tensile strength suitable for demanding joint loads. The 13 mm hex drive accepts a standard metric wrench or socket. The bright uncoated finish leaves the fastener in its natural steel state, making it appropriate for indoor or protected applications or for use where a specific coating will be applied on-site.
This cap screw is suited for general industrial, mechanical, and trade assembly work requiring metric hardware conforming to DIN 933 and ISO 4017 standards. Typical applications include machinery maintenance, HVAC equipment mounting, structural steel assembly, and fabrication environments where metric fasteners are specified. It is installed by millwrights, pipefitters, HVAC technicians, industrial mechanics, and general trade professionals working with metric-threaded components.
Designed as a standard metric replacement or assembly fastener conforming to DIN 933 and ISO 4017 dimensional specifications, fitting any application calling for a fully threaded M8 x 1.25 x 110 mm hex head cap screw in Grade 8.8 steel.
Installation should be performed by a qualified tradesperson using a properly sized 13 mm metric wrench or socket to avoid rounding the hex drive. Verify thread engagement depth and mating thread condition before torquing. Grade 8.8 fasteners require torque values specified by the equipment manufacturer or applicable engineering standards — do not substitute torque values from memory or from different grade hardware. Minimum order quantity for this item is 50 units.
