The Facom 440 Combination Spanners are designed to combine compactness with strength. They ensure maximum user safety, and when a critical tightening torque is reached, the wrench is distorted gradually, meaning no breaking is likely to injure the user. Dimensions meet the requirements of tooling standards NF ISO 1711-1 and aerospace standard SAE AS 954G. Tightening is guaranteed significantly above specifications of high strength tooling and bolting standards ISO 898-1. Sizes: 7, 8, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 22 & 24mm Ref: UTTK13328
