Anchor Fasteners Bolt

Product Description

Anchor fasteners are heavy-duty expansion bolts designed to secure objects into solid concrete, brick, or stone. Unlike standard wood or metal bolts, these use a mechanical expansion mechanism to "grip" the sides of a pre-drilled hole, providing immense pull-out resistance.

Types of Anchor Fasteners

• Wedge Anchors: The most common heavy-duty anchor. As the nut is tightened, a specialized wedge expands against the concrete. These are ideal for structural steel, heavy machinery, and racking.

• Sleeve Anchors: These feature a sleeve that expands along its entire length. They are more versatile and can be used in both solid concrete and hollow masonry or brick.

• Drop-In Anchors: Used for flush-mounting. You drop the anchor into a hole and use a setting tool to expand it. These are frequently used for overhead pipe suspension or handrails.

Selection by Environment

• Zinc Plated: Best for indoor, dry environments where moisture is not a concern.

• Galvanized: Provides a thicker protective layer for outdoor construction and framing.

• Stainless Steel (304/316): Essential for high-moisture, coastal, or chemical areas to prevent structural failure due to rust.

Recommended Anchor Options

Grip-It Stainless Steel Wedge AnchorA high-grade 304 stainless steel wedge anchor that provides reliable hold for outdoor fixtures like deck posts or fencing. Its corrosion resistance ensures the anchor won't seize or weaken over time.

B K JAGAN & CO Heavy Duty Sleeve AnchorThis M10 x 100mm sleeve anchor is designed for heavy-duty applications. It is particularly effective in masonry and brick where a wider expansion area is needed to distribute the load.

Hillman 1/2-in Drop-In AnchorIdeal for flush-mount applications such as mounting machinery to a shop floor or attaching handrails. Once set, the bolt can be removed and replaced without losing the anchor's position.

Installation Tips

1. Drill Depth: Always drill the hole slightly deeper (approx. 1/2 inch) than the anchor length to allow for any dust or debris that falls into the hole.

2. Cleaning: Use a blow-out bulb or vacuum to remove all dust from the hole. Debris can prevent the expansion mechanism from gripping properly.

3. Torque: Do not over-tighten wedge anchors, as this can cause the concrete to crack. Use a torque wrench to meet the manufacturer's specific requirements for the bolt size.
