Shock Absorber Screw

The Shock Absorber Screw secures the reservoir tube base in place. We make it from SCM435 alloy steel for dependable strength. The head comes in either socket head or hex flange styles. We use a cold header to form the head in a single operation. After forming, we roll the threads. This process hardens the thread surface and helps prevent stripping. Our product also has a chamfered shank for quick insertion during assembly.

Our technical team has over five years of experience. They can provide advice on fastening thin-walled parts. We offer non-standard sizes with diameters from M6 to M20. Lengths are made according to your drawings. Production time depends on the design complexity. Simple Shock Absorber Screw orders can be shipped within seven days. Complex orders usually take about fifteen days. We send production photos by email so you can keep track of your order status.

We use Japanese-brand Dacromet coating liquid to maintain consistent coating quality. After coating, the friction coefficient stays between 0.12 and 0.18. This range allows precise torque control during assembly. We also offer zinc-nickel plating with a bright silver appearance. We accept payments in RMB and USD. Our factory is located near Ningbo Port, and we can help arrange freight forwarding. Our Shock Absorber Screw is packed to provide reliable rust protection during sea transport.
