Value Collection 644262PS Hex Head Cap Screw M20x2.50x160mm

Product Description

The VALUE COLLECTION 644262PS is a metric hex head cap screw designed for general industrial fastening applications. This partially threaded fastener carries a Grade 8.8 strength rating, indicating a tensile strength suitable for structural and mechanical assemblies where a reliable bolted joint is required. The screw measures M20 x 2.50 thread pitch with a 160 mm length under the head and uses a 30 mm hex drive. It is manufactured from steel with a bright, uncoated finish and conforms to DIN 931 and ISO 4014 standards. Installation is performed by millwrights, maintenance technicians, and mechanical assemblers working on machinery, equipment frames, and structural connections.

This fastener is suited for metric bolted assemblies in manufacturing, heavy equipment, and industrial maintenance settings. The partially threaded shank provides a bearing surface in the grip zone, making it appropriate for applications where clamp load distribution across the joint is important. The DIN 931 and ISO 4014 conformance ensures dimensional interchangeability with other metric hardware sourced to those standards. Typical uses include machinery frames, steel fabrications, and equipment mounting applications requiring M20 hardware.

Key Features

• Grade 8.8 steel construction for reliable tensile and yield strength in structural assemblies
• Partially threaded shank per DIN 931 and ISO 4014 for consistent grip-zone bearing
• M20 x 2.50 thread pitch with 160 mm length under head for deep-reach fastening
• 30 mm hex drive compatible with standard metric wrenches and sockets
• Bright uncoated finish for use in dry indoor environments or where coating is applied post-assembly
• Metric thread standard ensures dimensional compliance with ISO 4014 and DIN 931 specifications

Compatibility

Designed as a standard metric replacement or new-installation fastener for any M20 x 2.50 bolted joint conforming to DIN 931 or ISO 4014 dimensional requirements.

Installation Notes

Installation is typically performed by mechanical technicians or millwrights using a 30 mm combination wrench or socket. Always verify thread engagement depth and joint design before final torque. Follow applicable machinery or structural engineering specifications for proper clamp load — do not exceed the torque requirements defined by the joint design engineer. Inspect threads on both the fastener and the mating nut or tapped hole before assembly to ensure clean engagement.
