Stainless Steel Nail In Anchors

Stainless steel nail in anchors are composed of high-quality stainless steel casing and hardened special steel nails. During installation, you only need to insert the anchor bolt into the prefabricated hole and use an ordinary hammering tool to knock the steel nail in. The casing will expand radially and form a strong mechanical lock with the base material. Taking a six-mm-diameter anchor bolt as an example, on a concrete base material with a strength grade of C20, the ultimate tensile bearing capacity measured according to the standard pull-out test can reach 3.2,000 N. However, using the same test method on a hollow brick base material, the ultimate tensile bearing capacity can still be maintained at more than 1.5,000 N. , this data fully proves the anchor's wide adaptability to different base materials, and can meet the fixing needs of light pipe supports, cable trays and decorative components. At the same time, the installation process does not require special power tools, and it only takes about five seconds to complete the knock-in operation of a single anchor bolt, which greatly improves the efficiency of on-site construction.

The anchor is made of austenitic stainless steel. After continuous spraying for 800 hours according to the neutral salt spray accelerated corrosion test, no obvious red rust spots appeared on the surface of the anchor, indicating that it has excellent corrosion resistance and is suitable for long-term fixation in outdoor or high-humidity indoor environments. In addition, in the fatigue test simulating vibration loads, after the anchor was continuously loaded for 30,000 cycles at a frequency of 20 Hz and an amplitude of 2 mm, its preload retention rate still reached 92% of the initial value, effectively eliminating the risk of loosening caused by long-term micro-vibration, making it an ideal choice for situations such as electromechanical equipment bases or ventilation duct hangers that are subject to continuous dynamic interference.
