Field of Application:
For St 12, St 13, St 14, St 33, St 37, UST 37, RSt 37, other unalloyed steels up to a tensile strength of 470 N/mm2, plus aluminium and other soft metals. Particularly suitable for ventilation systems, air conditioning units, painting systems, containers, switch cabinets, illuminated advertising signs, fire protection doors, roller shutter casings, awnings etc.
Minimum screw length = clamping force + material thickness + drill tip length + 3 mm. The clamping effect of the conical square drive bit allows the screw to adhere to the bit and thus facilitates single-handed installation. Metal filings do not collect at the drive tip, which occurs when using a magnetic bit holder.
