Nylon lock nuts are indispensable components in various industries, providing secure fastening solutions for a variety of applications. With their unique design and trusted performance, these nuts provide reliability and peace of mind.

Hot dip galvanized bolts are fasteners that form a zinc iron alloy layer on the surface through hot-dip galvanizing process

B7 bolts are high-strength fasteners that are widely used in various industries because of their excellent mechanical properties and durability.

Carriage bolts are divided into large semi-round head carriage bolts (corresponding to standards GB/T14 and DIN603) and small semi-round head carriage bolts (corresponding to standard GB/T12-85) according to the head size. Carriage bolt is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be matched with a nut and is used to fasten two parts with through holes.
