Frequently Asked Questions
What is a mechanical screw starter and what is it used for?
A mechanical screw starter is designed to grip and hold a screw while it is being positioned and initially threaded. This aluminium screw starter is particularly useful for recessed, confined and difficult-to-reach screws where holding the fastener with your fingers or balancing it on a conventional screwdriver is difficult.
What type and size of screws will this screw starter hold?
This mechanical screw starter is designed for compatible slotted / flat head screws with approximately 4mm to 8mm head sizes. The twist-action tip engages with the screw slot and mechanically grips the fastener while it is guided into position. Always check that the tip engages correctly with the screw before use.
How does the twist-action screw holding mechanism work?
Position the tip of the screw starter into the slot of the screw and twist to activate the mechanical gripping mechanism. The tool then holds the screw while you position and start it in the threaded hole. Once started, the mechanism releases and automatically resets, allowing final tightening with the appropriate screwdriver or hand tool.
What is the magnetic end of the aluminium screw starter used for?
The opposite end incorporates a permanent magnet for retrieving dropped ferrous metal components, including compatible screws, nuts, washers and small fasteners. This is particularly useful when retrieving parts dropped into vehicle engine bays, machinery housings and other restricted-access areas.
Is this screw starter suitable for automotive and engineering work?
Yes. The combination of a mechanical screw-holding tip, 143mm reach and magnetic retrieval end makes it useful for automotive repairs, classic vehicle maintenance, mechanical engineering, machinery servicing, electrical equipment, assembly work and general workshop maintenance, particularly where slotted screws are located in awkward positions.
Can a mechanical screw starter be used to fully tighten a screw?
The tool is primarily intended for holding, positioning and initially starting slotted screws, rather than applying final tightening torque. Once the screw has engaged correctly with the thread, use a suitably sized screwdriver or appropriate fastening tool to complete the installation.
