About this item
- What You Get: The 304 stainless steel stud bolt set includes 20 screw rods, bolt diameter 4mm/0.16", thread length 13mm/0.51" on each side, total length 30mm/1.18". Each screw rod comes with 2 nuts, 2 square washers and 2 spring washers to ensure stable locking
- Applications: The double-end threaded stud bolt set is suitable for fastening connection needs of various equipment such as motors, pump bodies, valves, furniture frames, bathroom hardware, distribution boxes, electronic equipment, automobile repairs, etc, making it an excellent option for industry, DIY, and maintenance
- How to Use: Screw one end of the thread into the part to be fixed (such as the equipment hole); then after the other end passes through the connector, install the square washer, spring washer and nut in turn, and finally tighten with a wrench to form a loose-proof structure to ensure that the assembly is stable and durable
- Notes: Before placing an order, please confirm whether the size is appropriate and avoid excessive force during installation to avoid damaging the thread. If used in a highly corrosive environment, it is recommended to check regularly.
- Features: Made of 304 stainless steel, it is not easy to rust, corrosion-resistant, and high temperature-resistant. Standard thread ensures smooth screwing without slipping. The square gasket enhances friction, the spring washer prevents falling off, and improves long-term stability

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
