Stainless Steel Coiled Spring Pins work in corrosive environments.

Press Release Summary:

Offered in metric sizes with Ø2–Ø6 mm diameters and 8–50 mm lengths, 316 stainless steel Coiled Spring Pins feature 2¼-coil cross-section and compress when installed into host component. These self-retaining pins exhibit uniform strength and flexibility after insertion. To prevent hole damage and prolong assembly life, shock absorbing design dampens forces and vibration. Type 316 stainless steel, resistant to pitting, features nickel and molybdenum content that promotes chemical resistance.

SPIROL Introduces 316 Stainless Steel Coiled Spring Pins

Danielson, CT – SPIROL International Corporation is pleased to introduce a line of 316 stainless steel Coiled Spring Pins designed for applications used in highly corrosive environments.

Easily recognized by its unique 2¼-coil cross-section, Coiled Spring Pins are self-retaining pins that compress when installed into the host component. They are the only pins with uniform strength and flexibility after insertion. Their shock absorbing design dampens forces and vibration to prevent hole damage and prolong assembly life.

While all 300 series stainless steels are considered to be highly corrosion resistant, Type 316 exhibits superior resistance to pitting in more severe environments such as when submerged in seawater and when used in the petrochemical industry. This is due to the higher nickel content and, in particular, the addition of molybdenum which significantly increases the chemical resistance of this alloy.

SPIROL’s 316 Stainless Steel Coiled Spring Pins are offered in metric sizes with nominal diameters ranging from Ø2mm to Ø6mm and lengths from 8mm to 50mm.
