Product Details
This hardened concrete masonry nail assortment delivers reliable penetration and holding power in concrete, brick, and masonry substrates for trim attachment, frame fixing, and structural formwork applications. The 65Mn high-carbon steel construction hardened to HRC 50-58 provides the hardness necessary to penetrate concrete without bending or mushrooming, a critical distinction from softer Q235 nails that deform on impact.
The concertina groove shank design doubles pull-out resistance compared to smooth shank nails, preventing loosening under vibration and thermal cycling. Zinc plating provides general corrosion resistance for covered outdoor applications, while copper plating offers galvanic compatibility with copper roofing and flashing. Available in 7 diameters from 2.0mm to 5.0mm and 7 lengths from 25mm to 100mm, with flat, round, and countersunk head options to match every aesthetic and functional requirement. Compatible with standard hammers and pneumatic concrete nail guns, these nails are packed in 1kg to 5kg boxes for convenient job site distribution. OEM box branding and custom groove patterns support wholesale and retail programs.
