Value Collection -42801-1 M20x2.50 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42801-1 is an M20 x 2.50 metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Built from alloy steel with a black oxide finish, this fastener meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, indicating high tensile strength suited for demanding load conditions. The 50 mm length under head provides consistent clamping depth in fully threaded configurations. Machinists, millwrights, and maintenance technicians typically install these screws using a hex key or Allen driver.

This screw is appropriate for general industrial machinery, equipment assembly, fixture fabrication, and maintenance repair operations where metric M20 fasteners are specified. The fully threaded shank allows engagement along the entire length under head, making it well suited for through-hole and short-grip applications. The black oxide coating provides mild corrosion resistance and reduces light reflection in precision assemblies. This SKU ships in a minimum order quantity of 10 pieces.

Key Features

• Hex socket drive accepts standard hex key or Allen wrench tooling

Compatibility

Designed as a standard M20 x 2.50 metric hex socket cap screw conforming to DIN 912 geometry, suitable for use in any application specifying that thread form and drive type.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using an appropriately sized hex key or Allen driver. Always ensure the mating threaded hole or nut meets the same metric pitch specification before installation. De-energize and lockout-tagout all equipment before fastener replacement or maintenance work on live machinery. Do not mix metric and unified thread fasteners, and verify torque requirements against the equipment manufacturer's specifications for grade 12.9 hardware.
