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:
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:
Also known as welded nuts, these are melted at high temperatures and welded between products for secure fastening. Benefits include:
Carbon steel offers several key performance characteristics:
| 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 |
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:
