Product Specification

Carbon steel galvanized fixed shaft, serrated shaft wrapped in rubber, precision hardware component for tools

Fitter Tools (Core Categories: Clamping, Assembly, and Finishing Hand Tools)

1. Specific Categories and Application Scenarios

• Bench vises (fixed, movable, flat-jaw)
• Pliers (circlip pliers, locking pliers, slip-joint pliers, water pump pliers)
• Punches (round, flat, center)
• Chisels (flat, cross-cut, oil groove)
• Scrapers (flat, curved)
• Scribers, center punches, hand files, wire brushes, etc.

2. Key Material Selection Requirements

• Material Selection

   

  Core components preferably use chrome-vanadium steel (CR-V), high-carbon steel, or alloy tool steel.

   

  Bench vise bodies can use cast iron (HT200‑250) to balance rigidity and cost.
   
  • Chrome-vanadium steel: high toughness and impact resistance, suitable for locking pliers, circlip pliers, etc.
  • High-carbon steel: high hardness and good wear resistance, suitable for punches, chisels, scrapers, etc.
  • Cast iron: high rigidity and low deformation, suitable for stable vise bodies.
   
• Clamping Surface Treatment

   

  Clamping parts of vises and pliers must be serrated with wear-resistant materials to ensure firm grip and prevent slipping.

   

  Sharpness must be controlled to avoid scratching workpieces.

   

  Soft jaws (rubber, copper pads) are required for precision workpieces.
   
• Structural Strength

   

  Large tools such as bench vises need high-rigidity materials to avoid deformation under heavy loads.

   

  Moving parts (jaw opening/closing mechanisms) use wear-resistant materials to ensure smooth operation without jamming or looseness.
   
• Anti-rust Treatment

   

  Workshop environments involve oil and moisture, so anti-rust treatments such as blackening, phosphating, and chrome plating are required to extend service life.

   

  Precision finishing tools (e.g., scrapers) need polishing to prevent rust from affecting accuracy.
