SPAX Universal Screws T20 Countersunk Head WIROX 3.5 x 16 mm, 1000 Pieces 1191010350165

Wood, chipboard, MDF, plastics, and thin metal profiles often require pre-drilling, which slows down assembly and risks splitting the material. These SPAX universal screws with a 4CUT point and WIROX coating eliminate that step in most wood types, while the T20 Torx drive provides a secure, cam-out-resistant fit.

Who is it for

• 4CUT point reduces splitting and often removes the need for pre-drilling.
