FASTENER MANUFACTURING

From Wire Rod to Final Delivery

Fastener manufacturing typically covers incoming material inspection, material preparation, blank forming, heat treatment, surface treatment and packaging. Process selection depends on the fastener material, specification and production requirements. Material preparation may include spheroidizing annealing, pickling, phosphating, soaping and wire drawing. Forming may involve cold heading, hot forging, machining and thread forming. Heat-treatment operations include degreasing, dephosphating, cleaning, heating, quenching and tempering, followed by the specified surface treatment, rust protection and packaging.

Typical Manufacturing Process

  • Incoming Material Inspection

  • Material Preparation

  • Blank and Thread Forming

  • Heat Treatment

  • Surface Treatment

  • Packaging and Delivery

INDUSTRIAL FLUID APPLICATIONS

Critical Fluid Applications for Consistent Fastener Quality

Industrial fluids connect forming, cleaning, heat treatment, surface finishing and final protection. Their lubrication, cleaning, cooling and protective performance influences production efficiency, dimensional stability and delivery quality.

  1. AI illustration of unthreaded cold-headed fastener blanks

    Cold Heading and Thread Forming

    Cold heading, shank reduction, thread rolling and tapping involve high loads and continuous processing. Fluids must balance lubrication, extreme-pressure performance, foam control and workplace conditions to help limit forming defects and tool load.

  2. AI illustration of fasteners in a parts-cleaning basket

    Dephosphating and Cleaning

    Phosphate coatings, forming oils and other residues need to be controlled before heat treatment. After quenching, residual fluid and contaminants must be removed. Consistent dephosphating and cleaning prepare the surface for tempering, plating or blackening.

    Quenching and Distortion Control

    Mesh-belt and multi-purpose furnaces process fasteners in a range of sizes. Quenchant cooling stability, cleanability and operating condition influence hardness, microstructure, distortion of long components and subsequent surface finishing.

    Residual-Heat Blackening and Rust Protection

    Residual-heat blackening requires control of color uniformity, film adhesion and bath stability. Subsequent rust protection must be matched to the protective fluid, packaging method, storage environment and transportation period.

PRACTICAL APPLICATION RESULTS

From Cold Forming to Quench Distortion Control

Operating-condition analysis, fluid matching and application validation connect fluid selection with measurable production results. The following examples cover high-deformation forming and heat treatment of long fasteners.

Typical Applications

  • Shank Reduction, Cold Heading & Nut Forming

  • Thread Rolling & Tapping

  • Dephosphating & Pre-/Post-Heat-Treatment Cleaning

  • Oil Quenching

  • Water-Soluble Quenching

  • Residual-Heat Blackening

  • Inter-Process & Final Rust Protection

    Forming Conditions

    10B21 and SCM435 materials; sizes up to M22; shank reduction ratio of 65%–70%. Samples shown are illustrative.

    70 / 210

    Reported Production

    Approximately 70 pieces/min for M18 parts and 210 pieces/min for M7 parts.

    Cold Heading of High-Strength Fasteners

    At an automotive high-strength fastener manufacturer, forming fluids were applied to cold heading of 10B21, SCM435 and related materials in sizes up to M22. The operation achieved a shank reduction ratio of 65%–70%, with reported production speeds of approximately 70 pieces per minute for M18 parts and 210 pieces per minute for M7 parts. The application met lubrication requirements for high-deformation forming and replaced an imported product.

    100%

    KR6480 Result

    With KR6480, the reported fluid service period reached 7–8 months and die-gauge inspection recorded a 100% distortion pass rate.

    Quench Distortion Control for Long Fasteners

    In an M16 × 240 long-fastener application, distortion was reported after the original imported quenchant had been in service for three months. After switching to KR6480 water-soluble quenchant, the reported fluid service period extended to 7–8 months. Die-gauge inspection recorded a 100% distortion pass rate, while tensile strength results ranged from 898 to 929 MPa under the reported application conditions.
