5/16" Nut Setter 45mm | Magnetic Impact Bit – Lerin

The Lerin 5/16" Magnetic Impact Nut Setter is the go-to size for roofing and decking work, sized to suit the hex-head tek screws used on Colorbond roofing, metal decking, and fencing. The magnetic tip grips the fastener so you can drive one-handed on the roof or up a ladder, without dropping screws every second fix.

Rated for daily impact driver use, it's built to handle the torque and vibration of trade work fix after fix without stripping or failing. The 1/4" hex quick-release shank drops straight into any impact driver or drill with a standard quick-release chuck — no adaptors needed.

Ideal for roofers, decking installers, and fencing contractors working with 5/16" hex-head fasteners.
