Pin Type Anchor Bolts
Pin Type Anchor Bolts are heavy-duty fasteners designed for anchoring structural components, machinery, and industrial equipment into concrete foundations. These bolts provide secure embedment and high pull-out resistance, ensuring long-term stability in seismic, high-vibration, and heavy-load applications.
At Rajal Industries, we manufacture precision-engineered pin type anchor bolts that conform to ASTM and IS standards, ensuring exceptional tensile strength, corrosion resistance, and durability. Our pin type anchor bolts are widely used in construction, bridges, power plants, and industrial installations.

Head & Anchor Design Specifications
Embedded Pin Type Design for Secure Anchoring
- The pin expansion mechanism ensures a strong grip in concrete, preventing loosening under dynamic loads.
- Provides higher pull-out resistance than standard anchor bolts.
Straight, L-Type, and J-Type Configurations
- Available in various embedded designs to suit different foundation and installation requirements.
- L-Type & J-Type Pin Anchors enhance mechanical grip, ensuring reliable load transfer.
High-Precision Threading & Machined Body
- Ensures accurate engagement with nuts and washers, preventing slippage.
- Available in coarse and fine thread profiles for improved load distribution and secure fitment.
Thread Specifications & Precision Engineering
| Thread Type | Description | Application |
|---|---|---|
| Coarse Thread (UNC/ISO Metric) | Provides high durability and easy installation | General construction, foundation anchoring |
| Fine Thread (UNF/Metric Fine) | Allows higher clamping force and precise load distribution | Heavy machinery, seismic structures |
| Fully Threaded Anchor Bolts | Enables full adjustability and deep embedment | Adjustable base plate connections |
| Partially Threaded Anchor Bolts | Provides higher shear strength and better clamping | Structural anchoring, bridge supports |
Thread Fitment & Compliance
- Metric threads conform to ISO 6g tolerances, ensuring secure and stable anchoring.
- Imperial anchor bolts adhere to ASTM F1554 and ASME B1.1 specifications.
Corrosion Resistance & Environmental Suitability
Pin Type Anchor Bolts are exposed to outdoor, industrial, and corrosive environments, requiring protective coatings to extend their lifespan.
| Coating Type | Corrosion Protection Level | Ideal Applications |
|---|---|---|
| Plain Steel (No Coating) | Low | Indoor applications |
| Zinc Plated (Yellow/Blue/White/Black) | Moderate (48-96 hours SST) | General construction, low-exposure environments |
| Hot-Dip Galvanized (HDG) | High (600+ hours SST) | Outdoor structures, bridges, heavy industrial installations |
| Epoxy-Coated Anchor Bolts | Extreme | Chemical plants, marine structures |
| Geomet/PTFE Coatings | Extreme (1000+ hours SST) | High-performance industrial and offshore applications |
Salt Spray Testing (SST) per ASTM B117 & ISO 9227 ensures long-term rust prevention and durability.
Common Applications of Pin Type Anchor Bolts
