Chipboard screw VELOX® SIT blue zinc plated, partial thread

High Performance from tip to head

Description

The fast chipboard screw VELOX® SIT 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!

The patented tip thread area reduces splitting of the wood and installation torque. This is for flush fitting and a longer battery life. The sliding coating enables an additional torque reduction.

Diameters Ø3,5 and Ø6 of the chipboard screw VELOX® SIT with partial thread have external underhead milling ribs for flush fitting and fewer wood shavings on the surface while Ø4 Ø4,5 and Ø5 have internal underhead milling pockets especially suitable for metal fittings.
