Setscrew for Terex RT 335

The 312-3318 setscrew is a headless fastener used to secure components against a shaft or within a housing. By sitting flush with the surface, it allows for a compact design that prevents interference with moving parts and minimizes debris accumulation in tight mechanical spaces. This component is compatible with the Terex RT 335 rough-terrain crane, where it is used to maintain the alignment and position of parts within transmission systems, slewing mechanisms, or boom extension assemblies.

This fastener is manufactured to the specific dimensions of 3/4 inch thread diameter and 2-1/2 inch length. Proper installation ensures that gears, pulleys, or other rotating elements remain fixed under operational loads and vibrations. Using the correct fastener is necessary to prevent component slippage, mechanical misalignment, or excessive play within the machine systems.

Setscrews function by exerting pressure against a shaft or mating surface to lock two parts together. They are commonly used in machinery to fix timing gears, pulleys, or collars in a precise relative position. By providing a secure, low-profile connection, these fasteners maintain the integrity of power transmission and control systems in heavy equipment.
