Sleeve Foundation Bolt manufactured by LG Industries is a type of mechanical anchor bolt used to fix steel structures, base plates, handrails, and equipment into concrete or masonry. It consists of a threaded bolt combined with an expandable metal sleeve that grips the concrete when tightened.
Design & Working Principle
Made of a threaded bolt, expansion sleeve, nut, and washer.
When the nut is tightened, the bolt pulls up, causing the sleeve to expand outward.
The expanded sleeve creates strong friction against the concrete, providing secure anchorage.
Suitable for post-installation, unlike cast-in foundation bolts.
Material & Finish
Common materials: Carbon Steel, Mild Steel, Stainless Steel (SS 304 / SS 316).
Surface finishes include zinc plated, hot-dip galvanized, or plain.
Corrosion-resistant options available for outdoor and industrial environments.
Sizes & Specifications
Diameter: Typically M8 to M24 (larger sizes on request)
Length: Depends on embedment depth and base plate thickness
Threading: Full thread
Supplied with nut and washer
