Stainless Steel Thimbles

A thimble supports the inside of a cable eye, helping preserve the bend shape and reduce crushing, abrasion and wear where the eye bears against a pin, shackle or other fitting.

Match the thimble groove to the wire-rope diameter and confirm the eye dimensions fit the mating pin or fitting. The cable should sit properly in the groove without being pinched or excessively loose.

These styles differ in material section, reinforcement and eye geometry. Standard and commercial designs cover many general applications, while heavy-duty and extra-heavy styles provide a more substantial bearing surface for demanding or high-wear assemblies.

304 stainless suits many general environments. 316 stainless normally offers better resistance to saltwater and aggressive marine exposure. Match the thimble grade to the cable, terminals, environment and project specification.

They are specification-oriented designs intended for assemblies that call for the corresponding dimensional standard. Do not substitute a similarly sized commercial thimble when a drawing, contract or regulated application requires a named specification.

A captive design helps retain the eye component in an assembly and can suit applications where controlled attachment geometry is important. Confirm compatibility with the selected cable and mating hardware.

Yes, when the cable, thimble and termination method are designed to work together. Follow the terminal or clip manufacturer’s spacing, turn-back, swaging and inspection requirements.

No. The completed assembly is limited by its weakest component and by the termination efficiency. Cable construction, terminals, installation, bend geometry, safety factor and application rules all affect the allowable load.

Rinse away salt and contaminants, and inspect the groove, crown and side plates for distortion, cracks, sharp wear, corrosion and cable movement. Replace damaged parts and any assembly that fails its applicable inspection criteria.
