Value Collection 643509PS M8x1.25x100mm Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643509PS is a fully threaded hex head cap screw conforming to DIN 933 and ISO 4017 standards. Sized at M8 x 1.25 with a 100 mm length under the head, it is manufactured from Grade 8.8 steel with a bright uncoated finish. The 13 mm hex drive size is compatible with standard metric wrenches and sockets. This fastener is suited for mechanical assemblies, structural connections, and equipment fabrication where a metric fully threaded hex cap screw with defined tensile properties is required. Installation is typically performed by machinists, millwrights, electricians, and mechanical contractors working to metric fastener specifications.

This screw is used in a wide range of industrial and trade applications including HVAC equipment assembly, electrical enclosure fabrication, pump and motor mounting, and general mechanical construction. Its full thread length along the 100 mm shank allows use with standard metric hex nuts, flanged nuts, or threaded inserts across the full grip range. The uncoated bright finish is suitable for dry indoor environments or applications where a secondary coating will be applied after assembly.

Key Features

• Fully threaded shank along the entire 100 mm length under head for maximum thread engagement
• Grade 8.8 steel construction provides defined medium-high tensile strength per ISO standards
• DIN 933 and ISO 4017 compliance ensures dimensional interchangeability with standard metric fasteners
• 13 mm hex drive compatible with standard metric open-end, box, and socket wrenches
• Bright uncoated finish allows for post-assembly coating or plating if required

Compatibility

Designed as a standard DIN 933 and ISO 4017 compliant fully threaded metric hex cap screw, suitable for use with any M8 x 1.25 threaded metric nut or threaded insert meeting the same standard.

Installation Notes

Installation should be performed by qualified tradespeople following applicable mechanical assembly codes and equipment manufacturer torque specifications. Use a properly sized 13 mm metric wrench or socket to drive the fastener. Do not mix metric and unified fasteners in the same threaded assembly. Verify thread engagement depth meets design requirements before applying final torque.
