Value Collection 815256PR Hex Cap Screw M20x2.5 140mm Grade 8.8

Product Description

The VALUE COLLECTION 815256PR is a metric hex head cap screw engineered for general industrial and mechanical fastening applications. Manufactured from Grade 8.8 steel with a zinc-plated finish, this fastener delivers reliable tensile strength and basic corrosion resistance in standard service environments. The partially threaded shank, sized at M20 x 2.50 thread pitch and 140 mm length under head, provides a smooth bearing surface for shear-loaded joints. The 30 mm hex drive accommodates standard metric wrenches. Conforming to DIN 931 and ISO 4014 standards, it is a recognized specification fastener suitable for structural and equipment assembly work performed by millwrights, maintenance mechanics, and industrial trades.

This cap screw is suited for bolted joint assemblies in commercial and industrial settings where metric fasteners are specified. Typical applications include machinery mounting, structural steel connections, equipment frames, and general fabrication requiring a partially threaded hex bolt in a larger diameter class. The M20 size is common in heavy equipment, conveyor systems, pump mounting, and similar load-bearing assemblies where Grade 8.8 strength class is required by design specification.

Key Features

• Grade 8.8 steel construction provides medium-high tensile strength suitable for structural bolted joints
• Zinc-plated finish offers basic corrosion resistance for indoor and semi-protected environments
• Partially threaded shank per DIN 931 and ISO 4014 standards allows the smooth shank to carry shear loads
• M20 x 2.50 thread pitch conforms to standard metric coarse thread specification
• 30 mm hex head accommodates standard metric open-end, box, and impact wrenches
• 140 mm length under head suits deeper grip applications common in heavy equipment assembly

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 931 and ISO 4014, suitable for use in any application requiring an M20 x 2.50 partially threaded Grade 8.8 fastener.

Installation Notes

Installation is performed by millwrights, maintenance mechanics, or qualified trades using standard metric hand or power tools. Always consult the joint design specification or engineering drawing for proper preload and torque requirements before installation. Ensure mating threads and bearing surfaces are clean and free of debris prior to assembly. Follow applicable codes and equipment manufacturer guidelines for fastener reuse and replacement intervals.
