Value Collection -42802-1 M20 X 2.50 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42802-1 is a partially threaded hex socket cap screw in M20 x 2.50 metric thread size with a 90 mm length under head. Constructed 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 suitable for demanding mechanical assemblies. The black oxide coating provides a measure of corrosion resistance and reduces light reflection in finished assemblies. This screw is installed using a hex socket drive and is suited for precision bolted joints in industrial, structural, and equipment fabrication applications.

This fastener is used in commercial and industrial settings where high-strength metric fasteners are required. Typical applications include machine frames, jigs, fixtures, heavy equipment, and structural assemblies that call for a socket-driven cap screw with a clean, low-profile head. Professionals in millwright, mechanical assembly, and fabrication trades commonly specify grade 12.9 alloy steel socket cap screws for critical clamping and load-bearing joints. Sold in a minimum order quantity of 5 units, with a package quantity of 1.

Key Features

• M20 x 2.50 metric thread with 90 mm length under head, partially threaded
• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• Black oxide finish for mild corrosion resistance and low-glare appearance
• Hex socket drive for high-torque installation in confined spaces
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard metric grade 12.9 hex socket cap screw conforming to DIN 912 and ISO 898-1, compatible with M20 x 2.50 threaded holes in industrial machinery, structural steel, and fabricated equipment assemblies.

Installation Notes

Installation is typically performed by millwrights, mechanical assemblers, or maintenance technicians using a calibrated hex socket wrench or torque wrench sized for M20 fasteners. De-energize and lock out all equipment before servicing any bolted assembly. Inspect threads and mating surfaces for damage or contamination before installation. Apply thread lubricant or threadlocker as specified by the equipment manufacturer for the joint design.
