L type foundation bolt

About L type foundation bolt

Technical Description L-Type Foundation Bolt

An L-Type Foundation Bolt is a heavy-duty fastener designed for securing structural elements to concrete foundations. It features a 90-degree bent L shape at one end, which provides strong anchorage once embedded in concrete. The straight threaded portion remains exposed above the surface for fastening equipment or structural components.

Key Technical Features

• Design: L-shaped anchor bolt with a bent hook (typically 90).

• Material Grade:

  • Mild Steel (MS)

  • Carbon Steel

  • High Tensile Steel (EN8, EN19)

  • Stainless Steel (SS304, SS316)

• Threading:

  • Partial or full threading as per requirement

  • Conforms to IS, DIN or ASTM standards

• Sizes Available:

  • Diameter: M8 to M64 (or as per custom requirement)

  • Length: 100 mm to 2000 mm and above

  • Bend Length: Customizable as per load requirements

• Surface Finish:

  • Self-color

  • Hot-dip galvanized

  • Electro-galvanized

  • Zinc plated / Black phosphate

• Standards Followed:

  • IS 1367

  • IS 5624

  • ASTM A307 / A325 / A490

  • DIN standards (on request)

Applications

• Industrial machinery installation

• Heavy equipment mounting

• Structural steel supports

• PEB structures & warehouse foundations

• Towers, poles, solar structures

• Concrete embedment anchoring

Advantages

• Strong grip due to bent hook anchorage inside concrete

• Excellent load-bearing and pull-out resistance

• Suitable for heavy vibrations, dynamic loads & structural support

• Long-term durability with anti-corrosion coatings

Manufacturing Process

• Cutting of steel rods to required size

• Accurate 90 bending using hydraulic bending machine

• Thread rolling or cutting as per specification

• Surface finishing (galvanizing/plating)

• Quality inspection for bend angle, thread accuracy & tensile strength
