Value Collection 815271PR M20x2.5 190mm Hex Cap Screw Gr8.8

Product Description

The VALUE COLLECTION 815271PR 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 solid tensile strength and basic corrosion resistance suited for structural and assembly use. The partially threaded shank measures 190 mm under the head with an M20 x 2.50 mm thread profile and a 30 mm hex drive. It conforms to DIN 931 and ISO 4014 standards, making it a recognized specification fastener for machinery, equipment frames, and fabricated assemblies.

This screw is intended for metric bolted connections in manufacturing, maintenance, and industrial construction environments. The partial thread design allows the unthreaded shank to bear shear loads while the threaded portion engages the nut or tapped hole. It is commonly installed by millwrights, maintenance technicians, and mechanical contractors working on equipment requiring heavy-duty metric fasteners. The M20 size and Grade 8.8 rating place it in the mid-to-high strength range for non-safety-critical structural work.

Key Features

• Grade 8.8 steel construction providing mid-to-high tensile strength for industrial fastening
• Zinc-plated finish for basic corrosion resistance in dry to mildly humid environments
• Partially threaded shank per DIN 931 and ISO 4014 for shear-load bearing capability
• M20 x 2.50 mm metric thread profile with 30 mm hex drive size
• 190 mm length under head suits deep-reach bolting in heavy assemblies
• Single-piece packaging with no minimum order restriction beyond individual unit

Compatibility

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

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with metric fastener standards. Always use a calibrated torque wrench appropriate for M20 fasteners and follow the equipment manufacturer's torque specifications for the assembly being serviced. Ensure mating threads and bearing surfaces are clean and free of debris before installation. Do not exceed the rated grade load by substituting this fastener in applications requiring higher-grade hardware such as Grade 10.9 or 12.9.
