Product overview

The fast chipboard screw VELOX® SIT/TX made of blue galvanized steel and with partial thread is perfectly suitable for mounting wood doors and windows, fittings, chairs or other wood furniture 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). Your advantage: only one bit size needed for four screw diameters!
