BS Cycle Thread Gauges

BS or BSCy Cycle Thread Gauge (i.e British Standard Cycle Thread Gauge) is prepared using a thread form adopted from the Cycle Engineers Institute (CEI) standards. It is a fine thread gauge well suited to cycle and motorcycle applications because it allows high torque settings and resists the tendancy to loosen under vibration. Unlike other major British imperial thread standards (like British Standard Whitworth and British Standard Fine) the thread runs at a 60 degrees rather than a 55 degrees angle.

We provide these BS Cycle Thread Gauge at reasonable prices and in specifications to the consumer needs. Our thread gauges can be availed in both regular and tailor made solutions to meet the specific requirements of our clients.

The majority of our cycle thread gauges are available to buy in a short lead time from our warehouses. Please contact us, to arrange these gauges for you.
