Value Collection 643235PS Hex Head Cap Screw M20 X 2.5

Product Description

The VALUE COLLECTION 643235PS is a metric hex head cap screw engineered for general industrial and mechanical fastening applications. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fully threaded fastener conforms to DIN 933 and ISO 4017 standards. It features an M20 x 2.50 thread with a 70 mm length under head and a 30 mm hex drive size. Grade 8.8 denotes a medium-high tensile strength classification suitable for structural and machinery assemblies where reliable clamping force is required. Licensed tradespeople, millwrights, and maintenance mechanics commonly install fasteners of this specification.

This hex head cap screw is suited for metric threaded assemblies in industrial machinery, structural steel connections, equipment frames, and general fabrication work. Its fully threaded shank allows engagement across the full length of the fastener, making it appropriate for through-hole applications where maximum thread engagement is needed. The DIN 933 and ISO 4017 compliance ensures dimensional interchangeability with metric hardware sourced from any compliant manufacturer.

Key Features

• Grade 8.8 steel construction provides medium-high tensile strength for demanding mechanical assemblies
• Fully threaded shank maximizes thread engagement in through-hole installations
• M20 x 2.50 thread pitch conforms to standard metric coarse thread specification
• 30 mm hex drive size compatible with standard metric open-end, box, and socket wrenches
• Meets DIN 933 and ISO 4017 dimensional standards for metric hex head cap screws
• Bright uncoated finish — suitable for use as-is or for post-installation coating or plating

Compatibility

Designed as a standard metric replacement or new-installation fastener for any application requiring a DIN 933 or ISO 4017 compliant M20 x 2.50 x 70 mm fully threaded hex head cap screw.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or tradespeople using metric open-end, combination, or socket wrenches sized to the 30 mm hex. Always confirm the mating thread is clean and undamaged before installation. Appropriate thread lubrication and torque values should be determined by the engineer of record or per the equipment manufacturer's specifications for Grade 8.8 hardware. Minimum order quantity is 10 units.
