Value Collection 643172PR Hex Head Cap Screw M16x2 80mm

Product Description

The VALUE COLLECTION 643172PR is a metric hex head cap screw designed for general-purpose fastening in mechanical assemblies, structural connections, and industrial equipment. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fully threaded fastener delivers reliable tensile strength for applications where a high-strength metric bolt is required. The screw follows DIN 933 and ISO 4017 standards, ensuring dimensional consistency and interchangeability across metric fastener applications. It measures M16 x 2.00 thread pitch with an 80 mm length under head and a 24 mm hex drive, making it compatible with standard metric wrenches and sockets used in trade and industrial settings.

This fastener is suited for use in mechanical fabrication, equipment maintenance, steel structural assemblies, and manufacturing line installations. The fully threaded shank allows engagement along the full length of the fastener, which is advantageous in through-bolting and thin-material applications. Maintenance technicians, millwrights, pipefitters, and general contractors commonly specify DIN 933 ISO 4017 hex cap screws for both OEM and field repair work where metric fastener standards are called out in engineering documentation.

• Fully threaded shank per DIN 933 and ISO 4017 standards ensures dimensional interchangeability
• 24 mm hex drive works with standard metric wrenches and impact sockets
• Bright uncoated finish suitable for indoor and controlled-environment installations

Compatibility

Designed as a standard DIN 933 and ISO 4017 compliant metric hex head cap screw for use in any application specifying an M16 x 2.00 x 80 mm Grade 8.8 fully threaded fastener.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or tradesperson following the applicable engineering torque specifications for Grade 8.8 M16 fasteners. Always use a calibrated torque wrench and apply the correct tightening sequence specified in the equipment or structure documentation. Inspect threads for damage before installation and do not substitute with lower-grade fasteners where Grade 8.8 is specified. No coating is present on this fastener, so consideration for corrosion protection may be required in wet or outdoor environments.
