Qimao Metal Manufacturer Industrial Equipment Used Double End Threaded Bolt Stud is built for industrial equipment that sees heavy vibration, thermal cycling, and constant load stress. Unlike standard studs that loosen over time, this one uses a precise thread fit and heat treated alloy steel to hold torque longer. We designed it for flanges, valve bodies, pump casings, and gearbox splits where a standard bolt just won't work. The blank center section gives you room for alignment while both threaded ends accept standard nuts or tapped housings. If your maintenance team is tired of replacing broken or stripped studs every shutdown, this one lasts longer and takes more abuse before it fails.

Qimao Metal Manufacturer Anti-Rotation Square Base Blind Weld Nut for Single-Side Welding material is low-carbon steel with a plain finish, though zinc plating is available on request. Thread sizes range from M4 to M10, with inch equivalents like #8-32 to 3/8-16. The square base measures about 15mm x 15mm for smaller threads, up to 25mm for larger ones. Total height from base to top is roughly 3-5mm depending on thread size. Recommended hole size in the frame is a snug square or round opening just 0.2mm larger than the pilot. Welding method: resistance welding or short-arc MIG works best. Max weld current 60A for 1 second. Temperature range after welding: -40°C to 150°C.

As a professional factory, Qimao Metal Manufacturer provides Long Life Under High Temp Brake Shoe Pin For Automotive Drum Brake System. This one is made specifically for high temperature zones inside the drum — where cheaper pins soften, bend, or wear an oval hole into the shoe web. We start with 40Cr steel, through-harden it instead of just case hardening, then apply a zinc flake coating that doesn’t burn off at 300°C. The pin diameter holds within 0.02mm, so it won’t wallow out the brake shoe hole after 50,000 miles. No slop, no clicking, no early replacement.

The hydraulic coil is a crucial part of the hydraulic system, usually made of enameled wire wound on the iron core, and the external insulation material is generally wrapped for protection.

High-precisino solenoid valve is an ideal solution for accurate fluid control. It combines advanced technology, high - quality materials, and a compact design. With rapid response and excellent sealing, it can work under a wide range of pressures and temperatures, suitable for various industrial and commercial scenarios.
