Stainless Steel Wedge Anchor Bolt

The conical wedge end pulls and expands the Wanluo’s China Stainless Steel Wedge Anchor Bolt tightly against the hole wall, forming a full-surface friction interlock with concrete, brick, stone and other base materials. It features ultra-high tensile strength, strong shear resistance and stable anti-loosening performance, solving the problems of low bearing capacity, easy loosening and falling off of traditional expansion bolts under load and vibration. Suitable for permanent fixed installation of engineering structures, mechanical equipment and building accessories, it is the most reliable anchoring solution for heavy-load building fixation scenarios.

Structural Features & Manufacturing Technology

The wedge anchor adopts integrated precision machining and overall heat treatment process, composed of high-strength bolt rod, conical wedge head, expansion sleeve, flat washer and hex nut. The precision polished conical wedge structure ensures uniform and full expansion of the sleeve without partial deformation or incomplete opening. The thickened expansion sleeve has high toughness and strong wall fitting performance, forming a large-area locking friction layer with the hole wall after tensioning. The full standard metric thread is rolled with neat and dense tooth profile, ensuring smooth locking and uniform force bearing. High-quality stainless steel and carbon steel materials are selected, with strict hardness and tensile strength testing. The overall structure is resistant to pulling, shearing and vibration, maintaining permanent anchoring stability in long-term outdoor and harsh engineering environments.

Usage and Maintenance

1. Professional wedge mechanical locking principle achieves full-surface expansion and fitting. Compared with ordinary expansion bolts, it has 3-5 times higher tensile force, effectively avoiding pull-out failure under heavy load and dynamic pressure.

2. Permanent one-way locking structure will not retract or loosen after installation. Stainless Steel Wedge Anchor Bolt has excellent vibration resistance and impact resistance, solving the problem of anchoring failure caused by equipment operation vibration and building structural shaking.

3. Strict high-strength material and heat treatment process ensure ultra-high structural stability. The bolt rod is not easy to break or deform, and the expansion sleeve is tightly locked without falling off, meeting the safety standards of engineering permanent fixation.

4. Simple and fast installation process, no special curing glue required. After drilling, cleaning and tightening, it can achieve instant locking and bearing, greatly improving construction efficiency and suitable for large-scale engineering construction.

5. Diversified material and surface treatment options adapt to indoor, outdoor, humid and coastal corrosive environments, Stainless Steel Wedge Anchor is widely used in building curtain walls, mechanical equipment fixing, highway guardrails, pipeline support, electrical engineering and infrastructure construction.

FAQ

Q1: What is the difference between Stainless Steel Wedge Anchor Bolt and ordinary expansion bolts?

A1: Ordinary expansion bolts rely on simple sleeve extrusion with small stress area and low bearing capacity, easy to loosen; wedge anchors adopt wedge conical mechanical locking, full-wall fitting, super high tensile and shear strength, permanent anti-loosening, suitable for heavy-load engineering fixation.

Q2: Can wedge anchors be removed after installation?

A2: Wedge anchors belong to one-way permanent locking fasteners. After full expansion and locking, they cannot be disassembled and rebound, which ensures long-term anchoring safety and is more suitable for fixed scenarios that do not need secondary disassembly.

Q3: What base materials are suitable for wedge anchors?

A3: Mainly used for high-hardness base materials such as solid concrete, cement walls, stone and hard bricks. Not recommended for hollow bricks, foam walls and loose lightweight base materials to avoid insufficient locking force.

Q4: Is the bearing capacity of stainless steel wedge anchors sufficient?

A4: Our 304/316L stainless steel wedge anchors maintain high tensile strength while possessing excellent corrosion resistance. They fully meet the heavy-load anchoring requirements of outdoor engineering, coastal facilities and humid environments.

Q5: Can customized lengths and special specifications be provided?

A5: Yes. We support customizing ultra-long, ultra-short, thickened and reinforced wedge anchors, as well as special surface anti-corrosion treatment to meet personalized engineering anchoring needs.
