Zipbolt UT Rail Bolt Photo


The ZIPBOLT™ UT – RAILBOLT uses the same boring configuration for bolts commonly used in the industry, with a very big difference. The use of a one-piece totally integrated gear system that replaces the old nut and washer. Assembly that simplifies joining parts together using common bits and drivers. Using a 5mm hex head driver, the installer no longer is trying to fit a nut and wrench into a 1″ hole. The hex is inserted into any adjustable torque drill, and makes tightening the gear head easy.

In addition to the Zipbolt UT Rail Bolt, Cleary has many products in stock for use in joining rail segments and fittings, newel post fasteners, post to post fasteners for balconies, angled railbolts for post to post on stairs. We also have exterior products for deck installation including post to post rail bolts and a post anchor.
