Eurotec OSB Fix screw, countersunk head, TX20 (4.3 x 45 mm)

Eurotec OSB Fix is a fully threaded wood construction screw designed for wood-based materials. It is made from tempered carbon steel with a yellow galvanized Cr3 surface and features a 60° countersunk head with milling ribs. The screw has a TX20 drive and a tip with scraping groove (type 17), which helps reduce the splitting effect during installation. According to the manufacturer, pre-drilling is not required.

The fully threaded design helps hold the board firmly in position and can help prevent creaking noises.
