Value Collection 644172PS Hex Head Cap Screw M16x2 80mm

Product Description

The VALUE COLLECTION 644172PS is a metric hex head cap screw intended for general mechanical assembly and structural fastening applications. It is manufactured from Grade 8.8 steel with a bright uncoated finish, making it suitable for applications where a protective coating is not required. The screw follows a partially threaded shank design, which helps maintain clamping force across joint interfaces. It conforms to DIN 931 and ISO 4014 dimensional standards. The thread size is M16 x 2.00 with a length under the head of 80 mm and a 24 mm hex drive size. Maintenance technicians, millwrights, and mechanical contractors install this type of fastener in equipment assembly and structural connections.

This cap screw is suited for metric fastening applications in industrial, commercial, and light structural environments. The partially threaded shank is appropriate for through-bolted joints where the unthreaded grip section spans the material being fastened. It is commonly used in machinery assembly, frame fabrication, equipment mounting, and similar trade applications where DIN 931 or ISO 4014 compliance is specified. The M16 thread size and Grade 8.8 designation make it a widely specified fastener across mechanical and structural trades.

Key Features

• Grade 8.8 steel construction for reliable tensile and yield strength in mechanical assemblies

Compatibility

Designed as an OEM-style metric fastener for use in assemblies requiring DIN 931 or ISO 4014 compliant hex head cap screws in M16 x 2.00 thread size.

Installation Notes

Installation of metric hex head cap screws is typically performed by millwrights, mechanical contractors, or maintenance technicians using standard metric hand or impact tools. Always confirm the mating thread and material grade requirements of the assembly before installation. De-energize or lock out any equipment before performing fastener work on mechanical systems, following applicable LOTO procedures. Do not substitute a lower-grade fastener in applications that specify Grade 8.8 or higher.
