Product Detail

Product Description

High Strength Carbon Steel Hexagon Head Bolts is recommended for machinery frames and fixture bases and related OEM fastening projects where Carbon Steel, Black Oxide, and Hexagon Head need to match the final assembly rather than a generic stock screw.

Typical Applications

  • Machinery frames and fixture bases.
  • High-strength fastening positions.
  • Industrial equipment assembly.

Parameter Notes for RFQ Review

  • Carbon steel is a cost-effective option for strength-focused assemblies and can be paired with protective finishes.
  • Black oxide or black zinc improves dark appearance and basic surface protection; confirm corrosion target if used outdoors.
  • A hex or hex socket style supports higher installation torque and controlled tightening.
  • The listed thread range (M10 M12 M14 M16 M18 M20 M22 M24 M27) indicates which metric or gauge families can be reviewed for the same product style. The length range (45mm-200mm) should be checked against clamping thickness, thread engagement and clearance behind the assembly.
  • Drive note: External hex drive or hex head geometry. Confirm driver access, assembly torque and whether service teams need matching tools.

Suitable OEM / RFQ Needs

Best fit for OEM/RFQ buyers who need machinery frames and fixture bases, high-strength fastening positions, with review of material (Carbon Steel), finish (Black Oxide), thread range (M10 M12 M14 M16 M18 M20 M22 M24 M27) and length (45mm-200mm). Send drawings, target quantity, application load/environment and any sample photos for a practical quotation.

Buyer Questions

  • Can this product be customized from a drawing or sample? Yes. XiYu can review drawings or samples for custom dimensions, material, finish, head style and production quantity. For this item, start from the listed Carbon Steel / Black Oxide direction and confirm any changes in the RFQ.
  • How should I choose the head and drive style? A hex or hex socket style supports higher installation torque and controlled tightening. Share the mating part, clearance and installation tool so the head and drive can be checked against the assembly.
  • What RFQ information helps speed up quotation? Provide thread size (M10 M12 M14 M16 M18 M20 M22 M24 M27), length (45mm-200mm), material, finish, drawing or photo, target quantity, application environment and whether samples are required.
  • Can samples be reviewed before bulk production? Sample review can be discussed for custom or production RFQs. For appearance-critical or functional screws, sample approval helps confirm finish, fit and assembly behavior before mass production.
