Product Introduction

Xinhong SDA nut is a dedicated matching component for hollow grouting anchor bolts. Forged from high‑quality alloy steel, it delivers high strength and stable load‑bearing capacity. Precisely machined threads ensure tight engagement and reliable anti‑loosening performance for efficient load transfer. Its unobstructed inner passage will not interfere with grouting operations. Easy to assemble and disassemble, it is fully compatible with matching anchor bolt parts. Subjected to multiple mechanical tests for good anti‑fatigue property, it suits geotechnical conditions of tunnels, mines, slopes and foundation pits to secure the whole support system.
