Metric Blue UST222850 Hex Head Cap Screw M20 X 2.50

Product Description

The METRIC BLUE UST222850 is a metric hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It carries a Grade 10.9 steel rating, indicating a tensile strength class suited for demanding clamping loads. The screw features a fully threaded shank with an M20 x 2.50 thread profile and a nominal length under the head of 65 mm. A 30 mm hex drive size allows installation with standard metric wrenches or impact tooling. This fastener is manufactured to DIN 933 standards, making it a recognized specification part for engineers and technicians sourcing metric hardware to documented tolerances.

This cap screw is used across a wide range of commercial and industrial applications including machinery assembly, structural steel connections, equipment mounting, and heavy fabrication work. Its fully threaded design makes it suitable for through-bolt applications or use with full-engagement nuts and threaded plates. The M20 thread size and Grade 10.9 rating are common in automotive, agricultural equipment, and industrial machinery maintenance. Trade professionals and maintenance technicians working on metric-specified equipment will find this fastener a direct match for DIN 933-compliant hardware requirements.

Installation Notes

Installation should be performed by qualified mechanical or structural trade professionals familiar with metric fastener specifications. Always confirm thread engagement depth and mating thread condition before installation. Use a calibrated torque wrench and consult the applicable equipment service manual or engineering specification for the required torque value, as Grade 10.9 fasteners carry specific preload requirements. Do not mix metric and imperial fasteners or substitute a lower-grade fastener in a Grade 10.9-rated joint.
