Introduction
Keyed Expansion Mechanical Anchors are engineered to provide robust and reliable fastening solutions for critical structural applications. Designed with M12 carbon steel, these anchors meet fire-rated IBC compliance, ensuring safety and durability in demanding environments. This article explores the product features, technical specifications, core applications, and company background of HEBEI HEX IMP. & EXP CO., LTD., a trusted provider of high-quality anchoring systems.
Product Overview
Keyed Expansion Mechanical Anchors are a specialized type of fastener designed for post-installed applications. They utilize a single-tube undercut mechanism to create a strong mechanical interlock with the substrate. This design ensures high load-bearing capacity and long-term stability in concrete and masonry structures.
Installation Guide
Step 1: Drilling
Drill a hole to the specified diameter and depth using a standard rotary hammer. Ensure the hole is thoroughly vacuumed to remove debris.
Step 2: Undercutting
Expand the base cavity using an undercutting drill bit. This step is mandatory for achieving a mechanical interlock.
Step 3: Insertion
Insert the anchor assembly until it is flush with the substrate surface.
Step 4: Tightening
Tighten the nut to 35 Nm torque, which activates the cone expansion mechanism.
Product Features and Advantages
The Keyed Expansion Mechanical Anchors offer several advantages, making them ideal for structural applications:
- High Load Capacity: Designed to withstand heavy loads in steel-to-concrete connections.
- Fire-Rated Compliance: Meets IBC (International Building Code) standards for fire safety.
- Seismic Resilience: Suitable for seismic bracing in earthquake-prone regions.
- Easy Installation: Simple four-step process ensures quick and efficient deployment.
- Durability: Constructed from M12 carbon steel, offering resistance to corrosion and wear.
