Tolerances
According to custom requirement. 
Normally the diameters tolerance is ±0.05mm.Length tolerance is ±0.1mm
But in many cases, we can achieve: diameters tolerance is ±0.02mm.Length tolerance is ±0.05mm

Material Selection
Cold Forging Pins, in use, according to their work requires selection. Connection with the sale, according to the diameter of the structural characteristics of the connection, according to an empirically determined, then a strength check if necessary. Can directly determine the structure of the positioning pins. Within each connector pin length, about 1 to 2 times their diameter.

Commonly used materials for 35 or 45 pin steel. Material safety pin for 35,45,50, T8A, T10A, etc., after the heat treatment hardness 30 ~ 36HRC. Sheath material available 45,35SiMn, 40Cr, etc., after the heat treatment hardness 40 ~ 50HRC.

Surface Treatment
