Description

The HECO-WS 7 × 133 mm is a structural screw with a countersunk head, Torx (HECO-Drive/T-Drive) recess. The 7 × 133 mm model pairs a thread under the head with white zinc protection for a joint that holds over time. Its point penetrates the wood without a pilot hole and limits splitting near the edges, including at the reduced spacings of the 7 × 133 mm size. This 7 × 133 mm size is intended for load-bearing joints in roof carpentry and timber structures. Packed in a box of 100 pieces, it is made by HECO under item number 53347. The chromium VI-free coating of the HECO-WS 7 × 133 mm supports even driving through to flush.
