Value Collection -42802-2 M20 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42802-2 is a metric hex socket cap screw designed for high-load fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a black oxide finish, this fastener meets DIN 912 and ISO 898-1 standards at material grade 12.9, indicating exceptional tensile strength suitable for demanding clamping and bolting tasks. The M20 x 2.50 thread profile with a 100 mm length under head makes it a common choice for machine frames, fixtures, heavy equipment, and precision assemblies. Installation requires a hex key or Allen-type socket drive. Sold in packages of 1, with a minimum order quantity of 5.

This screw is suited for use in manufacturing, maintenance, and mechanical assembly environments where high-strength metric fasteners are required. The partially threaded shank provides a smooth bearing surface along part of the grip length, which helps align mating components and resist shear loads. The black oxide coating offers mild corrosion resistance and reduces light reflection, making it appropriate for tooling, machine building, and industrial equipment applications.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• Black oxide finish provides mild corrosion resistance and a low-reflectance surface
• Partially threaded shank supports shear resistance and component alignment
• Hex socket drive (Allen key) for high-torque fastening in confined spaces
• Conforms to DIN 912 and ISO 898-1 fastener standards
• M20 x 2.50 thread with 100 mm length under head for deep-reach applications

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any M20 x 2.50 threaded application requiring a grade 12.9 alloy steel fastener.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated hex key or hex socket of the correct metric size. Always ensure the mating threaded hole is clean, undamaged, and properly tapped to M20 x 2.50 specifications before installation. Apply appropriate thread lubricant or threadlocker as required by the assembly specification. Do not substitute this fastener in applications requiring a different grade or thread standard without engineering review.
