Value Collection 643223PR Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 643223PR is a metric hex head cap screw designed for general-purpose mechanical fastening in industrial, commercial, and maintenance applications. Manufactured from Grade 8.8 steel with a bright, uncoated finish, it delivers reliable tensile strength suitable for moderate- to high-load assemblies. The screw features an M20 x 2.50 thread profile with a 35 mm length under head and is fully threaded along its entire shank. A 30 mm hex drive size allows installation with standard metric wrenches or sockets. Machinists, millwrights, maintenance technicians, and fabricators commonly install this fastener across a wide range of structural and equipment-mounting tasks.

This cap screw is well suited for machinery frames, fabricated steel structures, equipment bases, and general metalwork where a metric fully threaded fastener in the M20 size range is specified. It conforms to DIN 933 and ISO 4017 dimensional standards, making it a direct fit wherever those standards govern the design. The uncoated finish is appropriate for dry indoor environments or applications where a secondary coating or plating will be applied after assembly. Minimum order quantity is 10 pieces per order increment.

Compatibility

Designed as a DIN 933 and ISO 4017 compliant replacement or standard-service fastener for any assembly specifying a fully threaded M20 x 2.50 hex head cap screw in Grade 8.8 steel.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or maintenance technicians using a metric socket or box-end wrench sized to 30 mm. De-energize or lock out any equipment before fastener installation or removal in accordance with applicable LOTO procedures. Apply thread lubricant or threadlocker as specified by the equipment manufacturer or engineering drawings. Do not exceed the torque values specified by the assembly design documents, as overloading Grade 8.8 fasteners can cause permanent deformation or failure.
