Product Overview
This product is a pan head Phillips drive hi-lo thread concrete self-tapping screw. Made of a high-strength carbon steel substrate and an eco-friendly, chromium-free Ruspert coating, it is engineered specifically for hard substrates like concrete and lightweight walls. It requires no pre-embedded expansion anchors—it can be driven directly after pre-drilling. Combining convenient installation, high locking force, and long-lasting anti-corrosion, it adapts to various fastening scenarios in construction, home renovation, and outdoor engineering.
Product Applications
Widely applied in construction and home renovation (fixing wall shelves, curtain rods, air conditioner brackets), doors, windows, and curtain walls (connecting aluminum alloy/plastic-steel doors and windows to concrete), and outdoor engineering (outdoor railings, light steel joists, exterior wall cladding panels). It also adapts to fastening operations in lightweight walls like aerated concrete blocks and hollow bricks, as well as some hard substrates, serving as a highly efficient alternative to traditional expansion bolts.
