Value Collection 643505PR M8 X 1.25 X 90mm Hex Cap Screw

Product Description

The VALUE COLLECTION 643505PR is a metric hex head cap screw designed for general-purpose fastening in mechanical assemblies, fabrication, and equipment maintenance. It carries an M8 x 1.25 thread profile with a 90 mm length under the head and is fully threaded from the bearing surface to the tip. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fastener meets DIN 933 and ISO 4017 dimensional standards. The 13 mm hex drive is compatible with standard metric wrenches and sockets. Weighing 0.091 pounds per piece, it is a mid-weight fastener suited to structural and non-structural bolted joints alike.

This screw is used across a wide range of trade and industrial applications including HVAC equipment mounting, plumbing fixture assemblies, electrical enclosure hardware, and general mechanical maintenance. The fully threaded shank makes it well suited for through-bolt applications where the fastener engages a nut or threaded insert along the full grip length. It is appropriate for both shop and field assembly wherever metric hardware to DIN or ISO standards is specified.
