Value Collection 643162PR M16x2 Hex Cap Screw 55mm 8.8 Steel

Product Description

The VALUE COLLECTION 643162PR is a fully threaded hex head cap screw sized M16 x 2.00 with a 55 mm length under head. It is manufactured from Grade 8.8 steel with a bright, uncoated finish and a 24 mm hex drive. Grade 8.8 designates a medium-high-strength carbon steel fastener suitable for structural and mechanical assemblies requiring reliable clamping load. This screw conforms to DIN 933 and ISO 4017 standards, making it a widely accepted metric fastener for industrial, mechanical, and fabrication applications. Machinists, millwrights, maintenance technicians, and fabricators install this type of fastener in equipment assembly and structural connections.

This fastener is suited for general-purpose metric bolting applications in manufacturing, equipment maintenance, and fabrication environments. The fully threaded shank allows engagement along the entire grip length, which is useful in shallow-clearance joints or where a nut is used without a captured thread. The M16 thread size and Grade 8.8 rating are common in machinery frames, conveyor systems, HVAC equipment mounting, and industrial structural assemblies. It is sold in a minimum order quantity of 25 pieces per order.

Key Features

• Fully threaded shank allows nut engagement along the entire fastener length
• Grade 8.8 steel provides medium-high tensile strength for structural and mechanical joints
• 24 mm hex drive is compatible with standard metric wrenches and sockets
• Bright uncoated finish — no additional coating to account for in thread tolerance calculations
• Conforms to DIN 933 and ISO 4017 for dimensional consistency and interchangeability
• Metric thread standard ensures compatibility with ISO-standard nuts and tapped holes

Compatibility

Designed as a standard metric hex head cap screw for use with any DIN 933 or ISO 4017 compliant M16 x 2.00 nut or tapped hole in industrial and mechanical assemblies.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or fabricators using a standard 24 mm metric wrench or socket. Always verify that the mating nut or tapped hole is also Grade 8 or higher to avoid thread stripping under load. Torque to the value specified in the engineering documentation for the assembly — do not use a generic torque estimate without reference to the joint design. Inspect threads for contamination or damage before installation.
