Frequently Asked Questions
What is included in the Ullman Slotted Nylon Screw Starter Twin Pack?
The Ullman Tools Slotted Nylon Screw Starter Twin Pack contains two mechanical screw starting tools, measuring 68mm and 155mm in length. Both feature textured nylon bodies and mechanical gripping heads designed to hold, position and start compatible slotted-head screws. The shorter tool is useful for compact working areas, while the longer version provides additional reach. This listing includes both screw starters, but screws and other accessories are not supplied.
What screw types and sizes are compatible with the Ullman Nylon Screw Starters?
Both Ullman Slotted Mechanical Screw Starters are designed for selected #6, #8, #10 and #12 slotted-head screws. These numbers refer to screw size designations rather than screwdriver blade widths. Compatibility depends on the screw head's shape, dimensions and condition, so not every screw of the stated size will necessarily fit. These tools are not designed for Phillips, Pozidriv, Torx or Allen/Hex screw heads.
Can the Ullman Slotted Screw Starters hold non-magnetic screws?
Yes. The Ullman Nylon Screw Starters use a mechanical gripping mechanism rather than magnetic attraction, allowing them to hold compatible ferrous and non-ferrous screws. This makes them useful for positioning suitable steel, brass and other non-magnetic fasteners. The mechanical holder grips the screw head to help guide it into a restricted location and start the thread without needing to hold the screw with your fingers.
How do you use the Ullman Slotted Mechanical Screw Starters?
To use either Ullman Slotted Screw Starter, twist and retract the mechanical head to prepare the gripping mechanism. Align the holder with a compatible slotted screw head, then push towards the screw to engage the mechanical grip. Guide the screw into its required position and rotate the tool to begin threading. Once the screw has started, complete tightening using a correctly sized conventional screwdriver. These tools are intended for screw positioning and starting, not high-torque fastening.
Are the Ullman Nylon Screw Starters insulated and safe for live electrical work?
No. Although the textured nylon bodies provide electrical resistance, these Ullman screw starters are not confirmed as voltage-rated or certified insulated electrical tools. They must not be relied upon for protection against electric shock or used on live electrical equipment. They can be useful for positioning compatible screws during electrical maintenance, but the electrical supply must be safely isolated before work begins.
Why are the Ullman Slotted Nylon Screw Starters being sold as clearance stock?
These are original Ullman Tools USA end-of-line screw starters supplied without Ullman branding or branded packaging. As older clearance stock, the nylon bodies may show discolouration, surface marks or other age-related cosmetic imperfections. Their reduced selling price reflects this condition, and customers should not expect cosmetically pristine tools. The listing includes one 68mm and one 155mm screw starter, supplied together as a twin pack.
