Value Collection 643002PS M5x0.8 Hex Cap Screw 16mm Grade 8.8

Product Description

The VALUE COLLECTION 643002PS is a metric hex head cap screw designed for general-purpose mechanical fastening in a wide range of assemblies and structural applications. It features an M5x0.8 thread size with a 16 mm length under head and is fully threaded along its entire shank, providing consistent clamping force from head to tip. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fastener meets both DIN 933 and ISO 4017 standards. It is suited for use by maintenance technicians, industrial assemblers, and tradespeople who require a reliable metric fastener for equipment, fixtures, and mechanical assemblies.

This screw is appropriate for light- to medium-duty metric fastening applications in residential, commercial, and industrial settings. Its fully threaded design makes it well suited for through-hole applications and assemblies requiring maximum thread engagement. Conformance to DIN 933 and ISO 4017 ensures dimensional consistency and interchangeability with other metric fasteners meeting the same standards. It is commonly used in HVAC equipment assembly, electrical panel mounting, plumbing fixture attachment, and general mechanical maintenance work.
