Best screw in independent tests by British Woodworking Magazine:

‘Screw-Tite®’ extensively developed with the discerning craftsman/woman in mind, utilises the ‘Tri-Lock TS’ threadform which uniquely and cleverly incorporates the benefits of a single thread and a twin thread on the same screw, thus making it the most technically advanced screw available but more importantly the best performing woodscrew there is – a bold statement, we know, but we listened to what the user wanted and gave them just that.
