Product Details

Hex Bolt is supplied for machinery, steel structures, construction, equipment assembly and general fastening applications. The current supply reference is DIN 933 / DIN 931 / ISO 4014 / ISO 4017 / GB 5782 / GB 5783 / ANSI / ASME, with Carbon Steel / Alloy Steel / Stainless Steel, Zinc Plated / HDG / Black / Plain, and M6–M64/4.8.

Final dimensions, tolerances, grade or class, coating system, matched components, inspection documents and packing must be confirmed against the purchase order, approved drawing or project specification before production.

Selection & Use Steps

  1. Confirm the joint drawing, service condition and governing standard.
  2. Select grade or class, diameter, thread series, length, end configuration and matched nuts or washers.
  3. Specify finish, coating, lubrication, inspection documents and traceability requirements.
  4. Inspect markings, dimensions, threads and coating condition before assembly.
  5. Install using the project-approved tightening sequence, tools and engineering procedure.

Technical Drawing

Hex-head bolt technical catalog sheet with head-specific dimensions and reference geometry

The side elevation uses under-head length l, excluding the head. Confirm thread diameter d, thread length b, head height k and width across flats s in the separate end view. Partial thread is illustrated; full-thread, fine-thread and other variants require confirmation against the selected standard.

The illustration is a dimension-selection reference, not a manufacturing drawing and not to scale. Final geometry, tolerances, material, finish and mating-part fit must follow the buyer-approved drawing and applicable standard.

Application Environment

Suitable application depends on the confirmed material, grade, finish and project design. Review exposure to moisture, chemicals, salt, temperature, vibration and dissimilar metals before selection.

For outdoor or corrosive service, confirm that the selected coating or stainless grade is compatible with the required service life and installation method.

Installation & Handling Precautions

  • Do not mix grades, heat numbers, thread series or nut classes during storage and installation.
  • Protect threads and coatings from impact, contamination and uncontrolled repair.
  • Confirm nut and washer compatibility, coating allowance and free thread engagement before assembly.
  • Do not apply a generic torque value; tightening depends on lubrication, coating, joint design and the approved engineering procedure.
  • Replace components with damaged threads, uncertain identification or unacceptable coating condition.
