Product description
11mm Bi-Hex Nut Driver with Retaining Clip – Secure Fixing for Roofing and Cladding This bi-hex nut driver is designed for professionals and DIY users who need a reliable tool for driving tech screws and hex fasteners. The retaining clip feature sets it apart from standard nut drivers, holding fixings in place during positioning. Bi-Hex Design for Easier Access The 11mm bi-hex (12-point) profile offers multiple positions to engage with the fastener. Unlike standard 6-point drivers, this design requires less rotation to find alignment – particularly useful when working in tight spaces, at awkward angles, or overhead on roofing projects. Retaining Clip – No More Dropped Fixings A built-in retaining clip holds screws, washers and other fixings securely within the socket. Once the fastener is loaded into the driver, it stays in place until intentionally released. This feature is especially valuable when working on ladders, scaffolding or roofs where dropped screws mean wasted time and materials. Durable Chrome Vanadium Steel Construction Material: Chrome vanadium steel (Cr-V) Finish: Chrome plated Corrosion resistance: High Suitable for: Daily professional use The chrome vanadium steel construction provides the strength needed for repeated use without deformation.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
