Product Overview
M4 M16 Carbon steel Black finishing Dome Cap Nut Class 4.8 Grade 8.8 acron nuts

Cap nuts are used similarly to hexagonal nuts but feature a design that prevents the main nut from sliding easily. They require specialized tools for tightening, including live spanners, dull spanners, dual-purpose spanners (open part), or special square-hole socket spanners.

These nuts are primarily used for:

  • Rough and simple mechanical parts
  • Automotive applications (tires, front/rear axles of cars, tricycles, electric vehicles)
  • Road light frame bases
  • Equipment exposed to sunlight and rain
Nut Types & Applications
Hexagonal Nuts

Primarily used with bolts and screws for fastener connections. Classified by nominal thickness into Type I, Type II, and thin varieties. Type I nuts (for grades above 8) are further divided into A, B, and C levels:

  • A/B level: For machines/structures requiring smooth surfaces and high precision
  • C level: For rougher surfaces and lower precision requirements
  • Type II: Thicker design, ideal for frequent assembly/disassembly
Square Nuts

Also known as welded nuts, these are melted at high temperatures and welded between products for secure fastening. Benefits include:

  • Exceptional fastening security
  • Resistance to loosening
  • Wide applications in construction, transportation, and building materials
Material Properties

Carbon steel offers several key performance characteristics:

  • High strength: Withstands significant external forces and pressures
  • Durable: Maintains structural integrity under stress
  • Cost-effective: Provides excellent performance at competitive pricing
Carbon Steel Classification
Classification Method Types
By Use Carbon structural steel, Carbon tool steel, Free-cutting structural steel
By Smelting Method Flat furnace steel, Converter steel
By Deoxidation Boiling steel (F), Sedentary steel (Z), Semi-sedentary steel (b), Special sedentary steel (TZ)
By Carbon Content Low carbon steel (≤0.25%), Medium carbon steel (0.25%-0.6%), High carbon steel (≥0.6%)
By Quality Ordinary carbon steel, High-quality carbon steel, Premium steel
Strength Grade Compatibility

Bolt and nut strength levels typically match (e.g., 8.8 bolt with 8 nut). However, when nuts are harder to replace than bolts, using a slightly lower nut grade (e.g., 4.8 bolt with 5 nut) offers advantages:

  • Extended fastener system lifespan
  • Easier maintenance and replacement
  • Improved safety through controlled failure points
  • Cost-effective maintenance solutions
