Climax Metal Products ISTC-100-12 Threaded Shaft Collar

Product Description

The CLIMAX METAL PRODUCTS ISTC-100-12 is a one-piece threaded shaft collar designed to locate, space, and retain components on rotating or stationary shafts. Machined from steel with a black oxide finish, it features a 1-inch threaded bore with a 1-12 thread size, a 1-3/4 inch outside diameter, and a 0.5 inch width. The one-piece construction provides uniform clamping force and resistance to loosening under vibration. This collar belongs to the ISTC series and is manufactured under ISO 9001:2008 quality standards. It is installed by maintenance technicians and mechanical assemblers in industrial, HVAC, and power transmission applications.

This threaded shaft collar is suited for use in conveyor systems, pump assemblies, fan shafts, and general power transmission equipment. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies. Its compact 0.5 inch width makes it appropriate for installations where axial space is limited. The ISTC series is commonly specified in both OEM equipment builds and field repair or replacement scenarios across light and medium industrial environments.

Compatibility

Designed as an OEM-style replacement or new-installation threaded shaft collar for 1-inch threaded shafts requiring a 1-12 thread engagement in power transmission and mechanical assembly applications.

Installation Notes

Installation is performed by qualified mechanical technicians or maintenance personnel. Shut down and lock out all power to rotating equipment before installing or adjusting shaft collars. Thread the collar onto the shaft and position it at the desired location before tightening. Do not exceed the rated thread engagement and verify that mating shaft threads are clean and undamaged before installation.
