Value Collection UST181929 M8x1.25 Metric Hex Nut

Product Description

The VALUE COLLECTION UST181929 is an M8x1.25 metric coarse hex nut machined from steel with a metric blue finish. It features a right-hand thread direction and is sized at 13 mm across the flats and 6.5 mm high. This nut is a standard fastener used across mechanical, structural, and equipment assembly applications where metric coarse threading is specified. Tradespeople and fabricators reach for this part when securing M8-threaded fasteners in general-duty assemblies that do not require military-specification hardware.

This hex nut is suited for use in residential and light commercial mechanical systems, including HVAC equipment frames, electrical panel hardware, pump and motor mounting brackets, and plumbing fixture supports. Any application calling for an M8x1.25 right-hand metric coarse thread fastener is a typical fit. The metric blue finish provides a degree of corrosion resistance for indoor and sheltered installations.

Installation Notes

Installation does not require a licensed trade but is commonly performed by HVAC technicians, electricians, plumbers, and mechanical contractors during equipment assembly or service. Use a metric wrench or socket sized for 13 mm across flats. Power down or depressurize any system before replacing fasteners on live equipment. Do not cross-thread; hand-start the nut before applying torque.
