Product overview

The fast chipboard screw VELOX® SIT/TX made of stainless steel A2 and with full thread is ideally suitable for outdoor applications and obtains an ETA assessment ETA-12/0198 for use in timber construction. The SIT recess guarantees a perfect power transfer, fast mounting and a long-lasting SIT bit. Due the conial recess the screw will be centred (no tumbling) and sticks on the bit and improves your working comfort. Alternatively TX bits can also be used (without the mentioned advantages).
