The sealey 9 piece extra long hexagon allen key set delivers extended reach and versatility for working in recessed or hard to access applications. Manufactured from heat treated and hardened chrome vanadium steel with a satin chrome finish, this metric hex key set provides the durability and corrosion resistance required for professional use across automotive, machinery maintenance, and general engineering tasks. The extended length design, with keys ranging from 92mm to 235mm, makes this set particularly useful for reaching deep set fasteners in engine bays, machinery housings, and industrial equipment where standard length keys cannot reach. The comprehensive size range from 1.5mm to 10mm covers the most common metric hex socket requirements found in mechanical assembly and maintenance work. Each key is clearly marked for quick size identification, and the set is supplied in an easy access storage case with a hanging tag for organised workshop storage and efficient key selection. The hardened chrome vanadium steel construction ensures the keys maintain their shape under load, reducing the risk of rounding or stripping fastener heads during use.
