Value Collection 643233PR Hex Head Cap Screw M20x2.50x65mm

Product Description

The VALUE COLLECTION 643233PR is a metric hex head cap screw designed for general mechanical assembly and structural fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener meets the DIN 933 and ISO 4017 standards for fully threaded hex cap screws. The M20 x 2.50 thread size and 65 mm length under head make it well suited to medium-to-heavy bolted joint applications where a standard metric fastener is required. Machinists, millwrights, and maintenance technicians are the typical end users for this class of fastener.

This screw is used across a broad range of industrial, mechanical, and structural assembly contexts. Fully threaded along its 65 mm shank length, it provides consistent thread engagement throughout the joint. A 30 mm hex drive size accommodates standard metric wrenches and sockets. It is appropriate for use wherever DIN 933 or ISO 4017 fully threaded hex cap screws are specified in metric Grade 8.8 steel. Sold individually per package, with a minimum order quantity of 10 units.

Key Features

Compatibility

Designed as a standard DIN 933 and ISO 4017 fully threaded metric hex cap screw for use in any application specifying an M20 x 2.50 Grade 8.8 fastener.

Installation Notes

Installation is performed by millwrights, maintenance mechanics, or qualified assembly technicians using a metric socket or open-end wrench sized to the 30 mm hex. Always verify mating thread condition and ensure the tapped hole or nut meets the same metric thread standard before fastening. Apply thread lubricant or anti-seize compound only when specified by the equipment manufacturer or applicable engineering standard. Follow applicable torque specifications from the relevant engineering standard or equipment documentation for M20 Grade 8.8 fasteners.
