Sygma screw guide magnetic bit holders are ideal for projects where the user wants to prevent damage to his/her fingers. To make this possible, the retracting sleeve contains a magnetic core to prevent slippage and wobbling. Additionally, the magnet firmly holds and guides the screw inside the sleeve. The operator cannot touch the fastener inside the retracting sleeve.
Most importantly, heat treated S2 shock resistant tool steel maximizes durability and abrasion resistance.
