SPIROL introduces ArmorGalv, a thermal zinc diffusion coating, as a standard finish option for its engineered fasteners.

SPIROL specializes in quick turnaround delivery of high quality, precision engineered Shims ranging from simple OD/ID shapes to complex geometries – particularly in low to medium volumes.

Christie Jones / SPIROL International Corp. Precision shims are used as compensators to absorb tolerances between mating components. They significantly reduce manufacturing costs by eliminating the need for each component to be precision machined to achieve the proper fit and function of the total assembly. During the assembly, shims provide adjustment to compensate for accumulated…

As more assemblies change from metal to plastic, Engineers struggle with methods of joining “metal to plastic” or “plastic to plastic” without cracking plastic components. Essentially, metal compression limiters provide “spot” or local reinforcement of plastic components in high-stress joints typically where components mate (so the main housing can be manufactured from lower cost plastic).…

A recent brochure from Spirol Corp. covers many uses for coiled spring pins and the company’s many other specialty fasteners. The pins use a 2¼ coil cross-section to make them self-retaining pins that compress when installed into a host component. The manufacturer says they are the only pins with uniform strength and flexibility after insertion.…

Disc Springs look like conically-shaped washers, a shape that lets them take an axial load. They can be used individually or assembled into stacks for a required deflection. Spirol Disc Springs’ performance characteristics are predictable, letting designers calculate a minimum life cycle. They also provide high levels of load/force in a small space, unlike other…
