A roll bolt is a versatile mechanical fastener used to securely fix objects to concrete, masonry, or other solid surfaces. It consists of a bolt, an expanding sleeve, and a nut.
Key Features:
- Material: Typically made from stainless steel, carbon steel, or galvanized steel for strength and corrosion resistance.
- Design: Includes a threaded bolt with an expansion sleeve that locks the bolt in place when tightened.
- Sizes: Available in various diameters and lengths to suit different load requirements.
- Installation:
- Drill a hole in the base material.
- Insert the roll bolt.
- Tighten the nut, causing the sleeve to expand and secure the bolt.
Common Applications:
- Fixing heavy equipment, railings, and machinery to floors or walls.
- Mounting structural components like beams and brackets.
- Supporting suspended systems like HVAC ducts and cable trays.
Benefits:
- High load-bearing capacity.
- Durable and resistant to vibrations.
- Easy to install and reliable for long-term use.
