Value Collection 815971PS M20 Hex Cap Screw Grade 8.8 Zinc

Product Description

The VALUE COLLECTION 815971PS is a metric hex head cap screw designed for general industrial fastening applications. This fully threaded fastener measures M20 x 2.50 thread pitch with an 80 mm length under head and a 30 mm hex drive size. Manufactured from Grade 8.8 steel with a zinc-plated finish, it provides solid mechanical strength and basic corrosion resistance for structural and machine assembly work. It conforms to DIN 933 and ISO 4017 standards, making it a direct fit wherever those specifications are called out on engineering drawings or maintenance procedures. Millwrights, maintenance technicians, and mechanical contractors are the typical installers.

This cap screw is suited for metric bolted joint applications in industrial machinery, structural steel connections, equipment mounting, and general MRO maintenance. Its fully threaded shank and standard metric pitch make it compatible with any M20 x 2.50 nut or tapped hole. The zinc plating offers a baseline level of corrosion resistance appropriate for indoor or sheltered environments. It ships individually, making it practical for single-fastener replacement on the job or as a trial piece before committing to a larger quantity.

Key Features

• M20 x 2.50 thread pitch with 80 mm length under head for reliable load distribution
• Grade 8.8 steel construction provides high tensile and yield strength for demanding bolted joints
• Fully threaded shank per DIN 933 and ISO 4017 standards
• Zinc-plated finish for basic corrosion protection in sheltered applications
• 30 mm hex drive size compatible with standard metric wrenches and sockets
• Sold individually, suitable for single-fastener replacement or low-volume service work

Compatibility

Designed as a standard metric replacement fastener for any bolted assembly calling for an M20 x 2.50 hex head cap screw conforming to DIN 933 or ISO 4017.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with metric fastener torque requirements for Grade 8.8 hardware. Always verify the mating nut or tapped hole matches M20 x 2.50 thread specification before installation. Derate torque values when zinc-plated fasteners are used with lubricants, as coating affects friction coefficients. Follow applicable machinery manufacturer specifications and relevant industry standards for joint preload.
