Description
The VELOX, SIT/TX, SPS, BMax and BPL series for chipboard and wood have countersunk, semi-countersunk, pan, flat or washer heads, full or partial thread, PZ or SIT/TX drive, yellow or blue zinc plating, and A2 stainless steel is also available. For wood there are the DIN 571 with a hex head, the FTX71 with a locking washer, the TIC with an anti-cam-out drive, the BTW of A2 and the EDR stud screws. The SSG plasterboard screws have a coarse thread for a timber frame, the SSF a fine thread for a metal profile, the SSB a drill point for thick metal, the PVS goes onto a metal frame, the GGS joins board to board, and the GSH fixes gypsum fibre board. Self-tapping screws are made to DIN 7981, 7982, 7983, with an EPDM washer in the CH78 and DIN 7661 versions. Self-drilling screws comply with DIN 7504 K/N/P and DIN 7301, and with wings CBH, CBT, CBTON they fix PVC profiles, timber facades, vehicle bodies and phenolic panels. The thread-forming TRILOBULAR screws are represented by the TAPTITE 2000, TAPTITE II and POWERLOK. Metric screws DIN 84, 85, 933, 963, 965, 966, 7985, 7991 (DIN 7985 also in class 8.8 with TORX) are complemented by washers DIN 125, 9021, 7980, 6798, 7711, 7712, nuts DIN 934, 985, 6923 and caps.
How to choose
The decision depends on the material under the screw and on the environment. Plasterboard is fixed to a timber frame with SSG, to a thin profile with SSF or PVS, and to thick metal with SSB. For roofing there is a separate series, the hole is sealed by a screw with an EPDM washer, and outdoors A2 stainless steel is more appropriate than zinc plating. These screws are not used in concrete; the BTS B screw anchor with three embedment depths works there.

FAQ
How does the DIN 7504 self-drilling screw differ from the DIN 7981 self-tapping screw?
A DIN 7504 K/N/P screw drills the hole in the sheet itself, while a DIN 7981 self-tapping screw cuts a thread in an already drilled hole.
What are TAPTITE 2000 trilobular screws?
These are TRILOBULAR screws that do not cut but form the thread in metal. For serial assembly there is a separate industrial programme REMFORM / TAPTITE / PLASTITE.
Are there stainless steel screws?
Yes, screws for chipboard and wood are made of A2 stainless steel, and the BTW wood screws are made of it too.
Where are these screws made?
At the plants of a Spanish family group that has made fasteners for more than 50 years, also produces 1 million plastic plugs daily and supplies its products to more than 100 countries.
