Value Collection SCX220090-001BX M20x2.5 Socket Cap Screw

Product Description

The VALUE COLLECTION SCX220090-001BX is a partially threaded socket cap screw with an M20 x 2.5 thread and a 90 mm length under head. It features a socket cap head driven by a hex socket and is manufactured from 18-8 austenitic stainless steel in a bright, uncoated finish. Conforming to DIN 912, this fastener is suited for high-strength bolted assemblies where corrosion resistance and precise thread engagement are required. Machinists, millwrights, and maintenance technicians install this type of screw in structural, mechanical, and industrial fabrication applications.

This socket cap screw is used in applications where a recessed hex drive is preferred for torque application in confined spaces. The partial threading allows the shank to serve as a locating or shoulder element in bolted joints. Typical installations include machinery frames, equipment mounts, structural fixtures, and fabricated assemblies found in industrial, commercial, and heavy-duty maintenance environments. The M20 thread size and 90 mm body length make it well suited for medium-to-heavy fastening tasks requiring a robust metric fastener.

Key Features

• M20 x 2.5 thread size conforming to DIN 912 standard
• 90 mm length under head with partial threading for shank clearance fit
• Hex socket drive for high-torque application in tight spaces
• 18-8 austenitic stainless steel, material grade A2, for corrosion resistance
• Bright, uncoated finish — no coating buildup to affect thread tolerance

Compatibility

Designed as a DIN 912 metric socket cap screw for use in M20 x 2.5 threaded applications requiring an A2 stainless steel partially threaded fastener.

Installation Notes

Installation is typically performed by machinists, maintenance mechanics, or millwrights using a calibrated hex key or socket driver rated for the required torque. Always verify thread engagement depth and mating hole condition before installation. Clean threads of debris and inspect for cross-threading before applying torque. Follow applicable industry standards and equipment manufacturer torque guidelines for M20 fasteners in the specific joint material.
