Type

1. Hex Bolts & Hex Nuts

    • Used for joining heavy-duty structural components, machinery parts, and steel frameworks.

    • Available in full and half thread variants.

    • Manufactured from high-tensile steel, stainless steel (SS 304/316), or galvanized iron for corrosion resistance.

    • Complies with IS 1363, DIN 931/933, and ASTM standards.

2.Washers (Plain, Spring & Serrated)

    • Used to distribute load and prevent surface damage at bolted joints.

    • Plain Washers provide even load distribution.

    • Spring Washers offer tension to resist loosening from vibrations.

    • Serrated Washers provide grip and prevent rotation.

    • Available in mild steel, stainless steel, and hardened alloy steel.

3.Stud Bolts

    • Threaded rods with nuts on both ends, used for flange connections in pipelines and equipment.

    • Ideal for high-pressure and high-temperature environments.

    • Common in petrochemical, refinery, and power plant industries.

    • Available with PTFE, zinc, or hot-dip galvanized coatings.

4.Anchor Fasteners

    • Used to anchor structures or equipment to concrete or masonry.

    • Types include Wedge Anchors, Sleeve Anchors, and Chemical Anchors.

    • Provide strong holding power and vibration resistance.

    • Ideal for civil construction, heavy machinery bases, and load-bearing applications.

5.U-Bolts & J-Bolts

    • U-Bolts: Secure round pipes or tubes to walls, beams, or flat surfaces.

    • J-Bolts: Used for concrete embedment and support structures.

    • Made from galvanized iron, stainless steel, or zinc-plated carbon steel.

    • Common in plumbing, construction, and transportation equipment.

6.Socket Head Screws

    • Precision fasteners with internal hex drive (Allen key).

    • Provide high tensile strength in compact assemblies.

    • Commonly used in machine tools, die assemblies, robotics, and automotive components.

    • Available in button head, cap head, and flat head types.

7.Self-Tapping Screws

    • Designed to cut their own threads into soft materials like sheet metal or plastic.

    • Ideal for ducting, HVAC installations, enclosures, and light fabrication.

    • Available in stainless steel, zinc-plated, and black oxide finishes.

    • Options include pan head, countersunk, and hex washer head designs.
