Product Detail

Product Introduction

Titanium cotter pins provide simple mechanical retention for clevis pins, castellated nuts and other cross-drilled components in corrosion-sensitive assemblies. A complete order defines titanium grade, wire diameter, overall or effective length, eye geometry, equal or extended prongs, mating-hole diameter, installation method, service temperature and inspection.

Product Specifications

StandardISO 1234 and DIN 94 may be used as dimensional references for split cotter-pin forms when expressly invoked. Their standard material clauses do not automatically establish titanium supply; the purchase order must separately define titanium grade, condition, dimensions, testing and permitted deviations.Size & FormWire diameter, overall/effective length, eye geometry, equal or extended prongs and mating-hole data by drawing or invoked reference
ToleranceDrawing-defined wire, length, eye, leg alignment and functional fitSupply ConditionWire formed, trimmed, deburred, cleaned and lot identified

FAQ

Can a titanium cotter pin be reused?

A spread cotter pin is normally treated as a replace-on-removal retention item unless the approved maintenance procedure specifically allows reuse.

How is cotter-pin size selected?

Select wire diameter and length from the cross-hole, retained stack and required leg engagement, then verify installation clearance and material compatibility.

Are ISO 1234 dimensions enough for ordering?

No. Add titanium grade and condition, prong style, inspection, certificates and any dimensional deviations.
