DIYers and professionals, these SPAX expansion anchors are seriously game-changing for your mounting projects! This pack of 40 green nylon anchors (8.0x40mm size) gives you plenty for all your hanging needs around the house or job site. The brilliant 4-way spreading design distributes force evenly for optimal power distribution and really holds tight in the material. The dowel collar is such a smart feature - it protects your surface from damage and prevents the anchor from slipping too deep into the drill hole. The twist lock technology stops the anchor from turning when you're screwing in, which makes installation so much easier and more precise. What's really impressive is the expansion pressure-free dowel neck that prevents chipping on plaster or tiles - no more ruined finishes! These anchors work perfectly with SPAX partial threaded screws (obviously), but they're also compatible with all standard chipboard and wood screws. The high-quality nylon construction makes them incredibly stable, durable, and resilient for long-lasting performance. Whether you're mounting shelves, hanging cabinets, installing fixtures, or any project requiring secure fastening in various materials, these anchors deliver professional results. The green color makes them easy to identify, and the quality you get from the SPAX brand ensures your installations stay secure year after year. Stop dealing with anchors that strip out or don't hold properly - upgrade to these engineered anchors that actually work as promised!
