Value Collection -42802-3 M20 X 2.50 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42802-3 is a metric hex socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. It features an M20 x 2.50 thread size with a 110 mm length under head and is partially threaded. Manufactured from alloy steel with a black oxide finish, it carries a material grade of 12.9, indicating a high-tensile fastener suitable for demanding load-bearing connections. Licensed tradespeople and maintenance professionals working with heavy equipment, machinery, or structural steel frames will encounter this fastener type regularly.

This screw is suited for use in industrial maintenance, equipment assembly, and mechanical fabrication environments where metric fasteners with high tensile strength are required. The hex socket drive accepts standard Allen or hex key tooling. The partial thread length allows for firm clamping force in through-bolt applications where an unthreaded shank is needed to resist shear loads. This part is sold individually but requires a minimum order of 5 units.

Key Features

• M20 x 2.50 metric thread — standard coarse pitch for M20 fasteners
• 110 mm length under head with partial threading for shear-load applications
• Alloy steel construction with 12.9 material grade for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Hex socket drive accepts standard Allen or hex key tools
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for industrial equipment and machinery requiring M20 x 2.50 metric hex socket cap screws conforming to DIN 912 standards.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with metric fastener specifications. Always confirm the mating thread is clean, undamaged, and dimensionally compatible before installation. Use a calibrated torque wrench appropriate for 12.9-grade M20 fasteners and follow the equipment manufacturer torque specifications. Wear appropriate PPE when working with high-tension fasteners under load.
