1/2″ x 3″ Wedge Anchor Bolt – Maximum Tensile Strength for Shallow Concrete Fastening

The 1/2″ x 3″ Wedge Anchor Bolt is a high-performance structural fastener designed for load-bearing applications in solid concrete, particularly where minimal drilling depth is required. The size (1/2″ diameter and 3″ length) ensures strong, reliable holding power while accommodating thinner slabs or restricted drilling areas.

The core of its holding power lies in the wedge expansion mechanism : when the hex nut is tightened, the bolt pulls the tapered wedge clip up, forcing it to expand against the concrete wall of the pre-drilled hole. This creates a powerful, fixed anchor point. Constructed from durable zinc-plated steel, the anchor resists corrosion, providing a reliable, long-lasting solution for industrial and structural applications.

Key Benefits

• High Load Capacity: 1/2″ diameter provides high tensile and shear strength for structural applications.

• Shallow Embedment: Short 3″ length is ideal for concrete slabs where deep drilling is restricted or not required.

• Simple Through-Bolt Design: Allows the fixture to be installed directly over the anchor before tightening.

• Corrosion Resistance: Zinc-plated steel finish protects against rust and ensures long service life.

• Immediate Full Load: Achieves full specified load capacity immediately upon tightening (does not require curing time like chemical anchors).

Perfect For

• Anchoring structural steel components, base plates, and ledger boards to concrete.

• Securing vibrating or extremely heavy machinery and equipment.

• Installing heavy-duty rail systems, barriers, and industrial racking.

• Commercial and industrial construction requiring certified load ratings.

Application Instructions

• Drilling: Drill a hole (same diameter as the anchor, 1/2″) into the concrete to the required depth using a hammer drill.

• Cleaning: Clean the hole thoroughly of all dust and debris.

• Installation: Drive the anchor through the fixture (pre-drilled hole) and fully into the concrete hole.

• Tightening: Turn the hex nut with a wrench. This pulls the bolt up, setting the wedge and expanding the sleeve securely inside the concrete.

• Checking: Tighten to the manufacturer’s recommended torque.

Pro Tips

• CRITICAL: Use a hammer drill and a correct diameter carbide bit for a precise hole. The holding power depends on the correct hole size.

• Always clean the drilled hole thoroughly (brush and vacuum) to prevent concrete dust from inhibiting the wedge expansion.

• Do not use in soft materials like block or hollow brick unless specifically rated for those substrates.

• Ensure the anchor is embedded to the recommended depth for full load capacity.
