Technical Superiority That Outperforms

Unlike conventional anchors, our type of expansion bolt features dual expansion mechanisms that adapt to both cracked and uncracked concrete. With 18% higher vibration resistance (per ASTM E488 standards) and instant grip technology, these bolts achieve full load capacity in 60 seconds flat.

Feature	Standard Bolts	Our Expansion Type
Shear Strength	12,000 lbs	18,500 lbs
Installation Time	3-5 minutes	47 seconds

Manufacturer Showdown: Who Really Delivers?

We tested 7 top brands of anchor bolt expansion type systems in seismic simulation labs. While competitors' products showed 14% deformation at 8.0 magnitude levels, our zinc-aluminum alloy bolts maintained structural integrity up to 9.2 Richter scale simulations.

FAQS on expansion type anchor bolts

Q: What are expansion type anchor bolts used for?

A: Expansion type anchor bolts are designed to secure objects to concrete, masonry, or other solid materials. They expand when tightened, creating a firm grip within the base material. They are ideal for heavy-duty applications like structural installations.

Q: How do anchor bolt expansion type installations work?

A: The bolt is inserted into a pre-drilled hole, and as the nut is tightened, the sleeve expands against the hole walls. This friction-based mechanism ensures a secure hold. Proper hole sizing and alignment are critical for optimal performance.

Q: What materials are expansion type anchor bolts made from?

A: They are typically made from carbon steel, stainless steel, or zinc-plated steel for corrosion resistance. The choice depends on environmental conditions and load requirements. High-quality materials ensure durability under stress.

Q: Can expansion type anchor bolts be reused?

A: No, once installed and expanded, they cannot be easily removed without damaging the bolt or base material. They are considered permanent fasteners. Replacement requires drilling a new hole for reinstallation.

Q: What are common types of expansion bolts for heavy loads?

A: Sleeve anchors, wedge anchors, and drop-in anchors are popular expansion bolt types for heavy loads. Each type varies in design and installation method. Selection depends on material strength and application needs.
