Eurotec Paneltwistec - Recessed Head Wood Screws, Zinc Coated (5 x 40-120 mm)

Product description 
Paneltwistec wood screws are used as fasteners for load-bearing
timber structures between components made of solid timber, glued laminated 
timber, cross laminated timber and veneer laminated timber, as well as similar
wood-based materials, board-shaped wood-based materials or steel-timber
connections. Paneltwistec wood screws can generally be screwed in without 
any need for pre-drilling. The exception to this rule is when they are used in 
deciduous wood / hardwood.

The scraping groove on the screw tip ensures that the screws “grip” quickly, even 
in OSBs, for example. The cutting ribs downstream of the thread keep the shaft clear, 
so even long screws can be inserted with ease.

The special screw geometry reduces the splitting effect when screwing in.

Paneltwistec wood screws come in countersunk head and flange button head 
variants, and in coated carbon steel and a variety of stainless steels.
