Böllhoff standard 52030 | steel | zinc-plated, thick-film passivated (VZD) | Cr (VI) - free | self-tapping
QUICK FLOW® thin sheet metal screws are versatile sheet metal screws with a stable helix tip. They are used to permanently join even particularly thin sheets or components by secure and economical direct bolting. This thin sheet screw drills a hole in the sheet, forms a pull-through and then fears a metric thread.
Advantages:
• Replaces separate working steps such as punching, pre-drilling, tapping and thread cutting
• Repeated loosening and tightening possible
• Best suited for automated assembly
Surface (VZD): galvanized, thick-film passivated, min. 5μm | corrosion resistance to DIN EN ISO 9227*: white rust 72h, red rust 144h | defined coefficient of friction μ(total) = 0.12 - 0.18 for elements with a nominal tensile strength ≥ 800 MPa
*The verification of the mentioned minimum requirements is carried out according to the test conditions of DIN EN ISO 4042, galvanic coatings for fasteners. For dimensions < M5, the above values may deviate downwards.
