M4 SS304 Stainless Steel A2-70 DIN934 Hex Nut Hexagon Nut with Coarse Thread

The hex bolt is a fastening component with a hexagonal head. Its shank is threaded. By being used in conjunction with nuts and taking advantage of the frictional and mechanical interlocking effects of the threads, it applies clamping force to two or more components in various mechanical connection and building structure scenarios, thus achieving a stable connection.

1) Precise Thread Machining
2) High-Quality and Reliable Materials
3) Rich Surface Treatments
4) High Strength and Reliability
5) Advantage of Head Design.

1. Thread Specification:It covers metric threads (M) and imperial threads (UNC, UNF, etc.). Metric threads range from M3 to M64 and above, while imperial threads range from 1/4" - 4". The pitch is precisely set according to different diameters and standard series.
2. Bolt Length: The length range is wide, with supplies available from a few millimeters to hundreds of millimeters. Common lengths include 10mm, 20mm, 30mm, 50mm, 80mm, 100mm, 150mm, etc. The appropriate length can be precisely selected according to the specific connection structure and design requirements.
3. Strength Grade: According to international standards, multiple strength grade options from grade 4.8 to grade 12.9 are provided.
