Our hammer‑in split expansion anchor (drive anchor) is made of high‑strength carbon steel (Grade 4.8/8.8) or 304 stainless steel. Hammer‑drive quick installation – no tightening required; insert the anchor into the pre‑drilled hole and simply drive it in with a hammer. The integrally formed tapered tip forces the split expansion slots to expand against the hole wall, creating a secure anchorage. The flange with anti‑slip concentric rings increases bearing surface and prevents rotation. Sizes M6‑M16, lengths 30‑120mm custom. Suitable for load‑bearing walls, ceiling suspension, pipe supports, building studs, and handrail installations. Installation: drill → clean hole → hammer the anchor into the hole until the flange sits flush with the substrate – one‑step, no nut tightening required.

01
Hammer-in Quick Installation – One Step, No Nut Tightening
Hammer-in design – after inserting into the pre-drilled hole, simply strike the head with a hammer. The integrally formed tapered tip drives the split expansion slots outward, anchoring tightly against the hole wall. No wrench or special tools needed – one person, one hand. Ideal for overhead work, tight spaces, or bulk installations, offering several times faster installation than traditional expansion bolts, significantly reducing labor costs.
01
Flange + Concentric Anti-Slip Rings – Load Distribution & Rotation Prevention
The larger flange head provides greater bearing area, effectively dispersing loads and preventing hole-edge crushing or cracking. The bottom face features anti-slip concentric rings that bite into the substrate surface after driving, preventing rotation under vibration or lateral forces – ensuring stable anchoring orientation. Perfect for suspension brackets, pipe positioning, and railing installations – long-term reliability without loosening.
01
Quality Zinc Plating – Corrosion-Resistant, Wear-Resistant & Long-Lasting
Carbon steel substrate with eco-friendly yellow or blue-white zinc plating – dense and uniform coating resists moisture, dust, and mild corrosion, suitable for both indoor and outdoor use. The integrally formed tapered tip has no weld seams – won't crack under impact; the split expansion slots are hardened for repeated hammering without deformation. Fatigue-tested, this anchor withstands long-term static and dynamic loads without failure – extremely low replacement frequency, offering excellent value.
