The METRIC BLUE UST185123 is a metric hex head cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. Manufactured from Grade 10.9 steel, this fastener delivers tensile strength comparable to SAE Grade 8 inch-series hardware, making it suitable for demanding load-bearing joints. The M16 x 2.00 thread profile runs fully threaded along the 35 mm length under head, providing maximum thread engagement wherever the application requires it. A 24 mm hex drive allows installation with standard metric wrenches or sockets. This fastener is manufactured to ASME B18.2.3.1M, DIN 931, DIN 933, and SAE J1199 standards.
This screw is used across a wide range of industrial and mechanical applications where metric fasteners are specified. Typical uses include machinery frames, brackets, flanges, and equipment panels in commercial or industrial settings. The fully threaded configuration is particularly well suited for through-bolt applications or short-grip clamping scenarios where thread engagement along the full shank is advantageous. Maintenance technicians, millwrights, pipefitters, and mechanical contractors working on metric-spec equipment will encounter this fastener size and grade regularly.
Designed as a standard metric hex head cap screw for any application specifying an M16 x 2.00 x 35 mm fully threaded Grade 10.9 fastener per ASME B18.2.3.1M, DIN 931, DIN 933, or SAE J1199.
Installation should be performed by a qualified mechanic or maintenance technician familiar with metric fastener torque requirements for Grade 10.9 hardware. Always consult the equipment manufacturer's torque specification table before tightening, as proper clamp load is critical to joint integrity. Use a calibrated torque wrench with a 24 mm socket and ensure mating threads are clean and free of debris before assembly. Do not substitute a lower-grade fastener in applications specifying Grade 10.9.
