GI/HDG Spline Bolt

Size- 3/8 x 3/4″, 3/8×28, 3/8 x 1″
Grade- 4.8,8.8,10.9,12.9
Surface- Hot dip, Galvanized

GI/HDG Spline Bolt is a bolt with a special drive feature called spline drive and is coated with GI or Hot-Dip Galvanized for maximum protection against corrosion. They are primarily used for structural purposes, heavy-duty equipment, and aftermarket accessories intended for exterior use, where high strength and protection against rust are critical. Sourced from reputed Fasteners Suppliers in UAE to meet certain quality standards, these types of bolts are commonly used in place for installing equipment and structures.


Some Key Features:

Spline Design:
The head consists of the spline (multiple grooves) design augmenting torque, as well as providing anti-slip friction during installation. Stripping incidences are less as compared with ordinary Machine Screw or Phillips drives.

Material:
High-strength and alloy steel normally used, and sometimes combinations with Carbon Steel Bolts & Nuts can improve load-bear efficiency.

Corrosion Resistant:
Both GI and HDG coatings provide a cover against rust, thus increasing the lifespan—useful in systems where bonded straps and wire shields are also incorporated for added durability.


Application:

  1. Construction:
    For fastening structural parts of buildings and bridges, sometimes paired with SS Threaded Rod Bar or SS Flat Washers to ensure maximum integrity in installations.

  2. Outdoor Applications:
    Used in fencing and railing—another area where the use of utility poles is popular for casting sockets.

  3. Heavy Machinery:
    Suitable for strong, long-lasting fastener connections that are usually supported by SS Hexagon Bolts.

  4. Marine & Coasts:
    Performs well under salty conditions like stainless steel welded mesh is preferred for fencing and reinforcement under such zones.

  5. Fire and Smoke:
    These appliances show resistance to corrosion and rust, as well as resistance to damage due to harsh environmental influences; comparable to Brass Fasteners, which are only in certain industries mussy in terms of lifetime.


Additional Benefits:

  1. High Torque Capacity:
    The spline head ensures a secure grip and allows for high torque application unlike conventional fasteners.

  2. Versatility:
    Accepted across industries from those that use Stainless Steel Welding studs (Size: All types) or Copper Welding studs (Size: All types) for electrical and fabrication needs.

  3. Cost Effective:
    Long-lasting protection has greatly reduced maintenance and replacement costs as compared to ordinary suppliers of Stud in the UAE.
