Product introduction
Chanson Metals produce Stainless steel bolt with various type and sizes.
For uniform inch thread, the external thread has three thread grades: 1A, 2A and 3A, and the internal thread has three grades: 1B, 2B and 3B, all of which are clearance fits. The higher the level number, the tighter the fit.
1, 1A and 1B grade, very loose tolerance class, which is suitable for tolerance fit of internal and external threads.
2, 2A and 2B grades are the most common thread tolerance grades specified by the Inch series of mechanical stainless steel fasteners.
3, 3A and 3B grade, screwed to form the tightest fit, suitable for tight tolerance stainless steel standard parts, for critical design of safety.
Metric thread, external thread has three thread grades: 4h, 6h and 6g, internal thread has three thread grades: 5H, 6H, 7H. The thread fit is preferably combined into H/g, H/h or G/h. For the refined fastener threads such as bolts and stainless steel nuts, the standard is recommended to use 6H/6g.
