About this item
- ✓ Premium A2 Stainless Steel - Won't Rust in Rain or Humidity – Unlike cheap zinc-plated screws that corrode within months outdoors, our 304-grade stainless steel resists rust in garden furniture, decking, fencing, and outdoor projects. Not suitable for direct saltwater exposure (use A4 grade for coastal/marine). Maintains strength for years without degrading or staining wood.
- ✓ Flush Professional Finish – Pozi countersunk head sits completely flush with wood surfaces. No protruding screw heads to snag clothing or scratch skin. Ideal when appearance matters on visible furniture and joinery.
- ✓ Superior Grip in All Wood Types – Coarse thread design bites deep into softwood, hardwood, MDF, chipboard and plywood. Won't strip or loosen over time like cheaper screws. Holds securely even in dense materials.
- ✓ Easy Drive, Less Splitting – Pozi drive reduces cam-out (bit slipping) compared to Phillips head. Pre-drilling recommended for hardwoods to prevent splitting. Works with standard Pozi bits you already own.
- ✓ Why Choose A2 Stainless Over Cheaper Alternatives – Zinc-plated screws rust within 6-12 months outdoors. Brass screws snap under torque. Standard steel stains wood black. A2 stainless delivers superior corrosion resistance and structural integrity at professional-grade standard.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
