When it comes to fastening heavy loads to concrete, brick, or masonry, expansion bolts are the go-to choice. Also known as expansion anchor bolts or mechanical anchor bolts, these fasteners expand inside the base material to create a strong, reliable hold. HardHawk has been manufacturing premium anchoring systems for over 15 years, supplying stainless steel expansion bolts, heavy-duty wedge anchors, and custom mechanical anchors to customers worldwide.
What Are Expansion Bolts?
An expansion bolt is designed with a sleeve or wedge mechanism that expands as the bolt is tightened, locking the fastener securely into the base material. They are widely used in construction, infrastructure, industrial machinery, and safety-critical installations.
Our product range includes:
- Metric expansion bolts M6 to M24
- Lengths from 40 mm to 300 mm
- Wedge anchors, sleeve anchors, and drop-in anchors
Whether you need heavy-duty expansion bolts for concrete or custom stainless steel anchor bolts, HardHawk can provide the right solution.
Key Benefits and Applications
- Secure Anchoring: High pull-out and shear strength for safety-critical applications.
- Versatile Materials: Carbon steel zinc-plated, hot-dip galvanized, or stainless steel grades (SS304 / SS316).
- Easy Installation: No special tools required โ drill, insert, tighten, and the anchor expands.
