Casing Alignment Pin

A two-piece alignment system that reduces assembly time and increases safety when dealing with misaligned casing bolt holes.

Casing Alignment Pin

Product Overview

The Casing Alignment Pin is designed to reduce assembly time while increasing safety when dealing with misaligned casing bolt holes, performing the function of casing dowels. Conventional bolt alignment methods consist of bolt torque sequencing or hammering studs, which is time consuming and could lead to damaged components.

The Casing Alignment Pin solves this by using a two-piece alignment system consisting of a collet and tapered pin. This gives the user the ease of a drop-in installation while providing the angular force necessary to correct misalignment. The internal taper provides strong alignment forces and eliminates sliding damage in the hole. Custom solutions are available for specific applications and space requirements.
