Value Collection 42258 M8 X 1.00 20mm Hex Cap Screw 50pk

Product Description

The Value Collection 42258 is a metric hex head cap screw designed for general-purpose fastening applications requiring a strong, corrosion-resistant steel fastener. The screw features an M8 x 1.00 thread size with a 20 mm length under head and is fully threaded from tip to head. Manufactured from Grade 8.8 steel, it delivers a tensile strength appropriate for medium-duty structural and mechanical assembly work. A zinc-plated finish provides basic corrosion resistance for indoor and light-duty outdoor use. The 13 mm hex drive allows installation with standard open-end, box-end, or socket wrenches. Sold in a package of 50.

This screw is suited for metric fastening applications across manufacturing, maintenance, and light fabrication environments. The M8 x 1.00 fine thread pitch makes it appropriate for applications where vibration resistance or precise torque control is needed compared to coarse thread alternatives. Typical install scenarios include machine frames, equipment panels, brackets, and general mechanical assemblies where a fully threaded metric hex cap screw meeting DIN 961 and ISO 8676 standards is specified.

• Packaged in quantities of 50 per pack

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 961 and ISO 8676, suitable for use in any application specifying an M8 x 1.00 fully threaded hex cap screw in Grade 8.8 steel.

Installation Notes

Installation is typically performed by a mechanic, millwright, or maintenance technician using a 13 mm open-end wrench, box wrench, or socket. Verify thread engagement depth and mating thread condition before assembly. Do not exceed the torque rating specified by the equipment manufacturer for M8 Grade 8.8 fasteners. Ensure the mating component material and thread class are compatible with the fine 1.00 mm pitch before installation.
