Chain Bolt & Nuts Advantages / Features
Material using 35 forging, and modulation heat treatment processing technology to make the height of the screw and nut with the clearance more closely, not loose, wear-resistant, more tensile and compression resistance, not easy to break deformation, longer service life. The screw has two kinds of UNF and UNC and the tensile strength and compressive strength can reach 8.8-12.9.Bolt & Nut (Screw)production process

1.The screw is manufactured using 35Crmo forging wire in advance into a spiral shape.Because the wire will deform and become thicker after being forged,We need to choose a wire rod that is slightly thinner than the shaft of the screw when making the screw。 2.The material is conveyed to the appropriate length position and straightened by machine equipment, then it is fed to a cold heading machine.![](http://kehu02.grofrom.com/www.pingtaimachine.com/425419ac45b2a99b2535c66e79b99444.jpg)
