Description
The GB/T22795 Screw Type Expansion Anchor Bolts, commonly known as wedge anchors, are engineered for secure, vibration-resistant anchoring into solid materials like concrete. Manufactured from high-quality carbon steel or stainless steel, these anchors ensure robust performance, even under demanding conditions. The wedge design guarantees a firm hold by expanding upon tightening, making it ideal for structural and industrial applications.
Available in various grades (4.8, 5.6, 6.8, 8.8) and finishes such as zinc electroplating, hot dip galvanizing, and nickel plating, they meet multiple international standards (GB, DIN, ISO, ANSI/ASTM, BS, JIS). OEM customization is available per customer specifications.
