Ingco HHK11092 9-Piece Hex Key Set, 1.5–10mm, Cr-V

Our review

This is a nine-piece folding-style set of L-shaped hex keys from Ingco, covering the common metric sizes from 1.5mm up to 10mm. The keys are made from Cr-V steel, heat treated and chrome plated, and each has an extra-long arm, which helps when you need extra reach or more turning leverage on a stubborn bolt. It suits anyone doing furniture assembly, bicycle and motorcycle maintenance, or general repair work where small Allen bolts turn up. Before buying, check that the sizes match the fasteners you actually work with, since metric and imperial hex keys are not interchangeable, and confirm whether you prefer a loose set like this or a folding holder that keeps the keys together. Compare the steel type, size range and arm length against other hex key sets, and note that this one ships in double blister packaging.
