High-Quality M12 & M20 Brass-Plated Dome Cap Nuts T1 T2 T3 for Durable Metal Acron nuts

Cap nuts are used similarly to hexagonal nuts but feature a design that prevents easy sliding. They require specialized tools for tightening, including live spanners, dull spanners, dual-purpose spanners, or square-hole socket spanners.

These nuts are primarily used for:

• Rough and simple components in automotive applications (cars, tricycles, electric vehicles)
• Fixing road light frame bases
• Mechanical equipment exposed to weather conditions

Hexagonal Nuts: Used with bolts and screws for fastener connections. Classified by thickness into Type I, II, and thin varieties, with different grades for various precision requirements.

Square Nuts: Also known as welded nuts, these provide excellent fastening that resists loosening. Widely used in construction and transportation industries.

Flange Nuts: Feature integrated washers with non-slip tooth patterns for superior anti-loosening performance. Ideal for pipe connections and applications requiring firm, sealed joints.

T-Nuts: Designed to prevent rotation during installation, available in various shapes. Particularly useful for T-slot applications in milling machines.

Brass, an alloy of copper and zinc, offers excellent conductivity, thermal properties, elasticity, and mechanical performance. It's easily formed, welded, cut, and polished, making it ideal for:

• Electrical and thermal conductivity components
• Corrosion-resistant structures
• Sanitary ware and equipment manufacturing

Special Brass: Contains additional elements like lead, tin, or aluminum to enhance strength, hardness, and chemical resistance. Coded by composition (e.g., HPb59-1 indicates 59% copper, 1% lead).
