316 stainless steel coiled spring pins 15 May 2015

SPIROL International Corporation has introduced a line of 316 stainless steel coiled spring pins, designed for applications used in highly corrosive environments.

Easily recognised by their unique 2¼ coil cross section, coiled spring pins are self-retaining pins that compress when installed into the host component. SPIROL says that its pins are the only coiled spring pins with uniform strength and flexibility after insertion. The pins also feature a shock absorbing design that helps dampen forces and vibration to prevent hole damage and prolong assembly life.

SPIROL’s 316 stainless steel coiled spring pins are offered in metric sizes with nominal diameters ranging from 2mm to 6mm and lengths from 8mm to 50mm.

“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.”
