Product Features:
1. It is made of carburized carbon steel (99% of the total products), stainless steel or non-ferrous metal;
2, carbon steel tapping screws must go through carburizing treatment, stainless steel tapping screws must go through solid solution hardening treatment.
In order to make the tapping screw to meet the standard requirements of mechanical properties and performance;
3. The product has high surface hardness and good core toughness.
That is, "soft inside but firm outside".
If the surface hardness is low, it cannot be screwed into the matrix;
If the core toughness is poor, a twist on the broken, can not be used.
So "soft inside and firm outside" is the hexagon convex screw from tapping to meet the performance requirements.
4. The surface of the product needs surface protection treatment, generally electroplating treatment;
5. Adopting cold heading process for production.
It is recommended to adopt high speed cold heading machine and high speed wire rolling machine to ensure product quality.
This production of self-tapping screw head molding, thread quality is high.
PE bag + carton packaging shipping.
Tiansheng company specializes in r&d and production of non-standard fastening customized products for 12 years. You are welcome to customize products with drawings or samples.
