Special-Shaped Fastener

Product Description:

The Double Hexagon Step Adjustment Bolt is a novel type of fastener. It features a unique double hexagonal design on one end, which not only retains the tool compatibility of the traditional hexagonal head but also adds an auxiliary hexagonal structure, significantly enhancing installation convenience and torque-bearing capacity. The main body is made of 45# steel or stainless steel and is processed by precision CNC turning to ensure the thread accuracy (6g/6H grade). The intermediate step structure provides a stable supporting surface, and the surface is treated with galvanization/blackening to enhance corrosion resistance. It is particularly suitable for situations where space is limited but high-strength adjustment is required, such as precise mold positioning and assembly of automated equipment, and is an upgraded solution to traditional adjustment bolts.
