Industrial Applications

Hex Bolts / Screws are widely used in:

  • Electrical panels and assemblies: Provide secure and easy-to-maintain joints.
  • Automotive industry: Used in engines, chassis, and bodywork for robust fastening.
  • Construction and structural applications: Secure steel frameworks, beams, and building components.
  • Machinery and equipment: Ideal for fastening parts subject to high load and vibration.
  • Furniture and consumer products: Widely used due to availability and ease of use.

Product Description

Hex Bolts / Screws have a six-sided head that allows tightening using standard wrenches, spanners, or sockets. Available in both full-thread and partial-thread (to accommodate shear loads), they are manufactured to international standards ensuring interchangeability and quality. Precision threads provide high tensile strength, while various material and coating options afford corrosion resistance for indoor and outdoor use. With sizes spanning from small to heavy-duty bolts, hex bolts provide versatile solutions across industrial and commercial sectors.
