Why Choose Brass Castle Nuts?
Our brass castle nuts at AlbanyCountyFasteners.com, also known as brass slotted nuts, are hexagonal nuts with slots cut into the top, designed for use with a cotter pin to lock the nut in place, preventing rotation in high-vibration applications. Made from brass (typically 60% copper, 40% zinc), these nuts offer moderate corrosion resistance for indoor or low-corrosion environments, combined with a decorative gold-like finish. Their hexagonal shape allows easy wrench tightening. Available in imperial sizes like 1/4"-20, 5/16"-18, 3/8"-16 to 1"-8, they meet ASME B18.2.2, IFI tolerances, REACH, and RoHS standards, making them ideal for automotive, plumbing, and decorative projects requiring reliable locking and aesthetic appeal.
- Vibration Resistance: Slots enable cotter pin locking to prevent loosening.
- Moderate Corrosion Resistance: Brass suits indoor and low-corrosion settings.
- Decorative Finish: Gold-like appearance enhances visual appeal.
- High Standards: Compliant with ASME B18.2.2 for reliable performance.
Applications for Brass Castle Nuts

- Automotive and machinery components
- Plumbing and decorative fixtures
- Indoor industrial assemblies
- Furniture and architectural hardware
Frequently Asked Questions (FAQ)
Brass castle nuts are hexagonal nuts with slots cut into the top, made from corrosion-resistant brass, designed for cotter pin locking to prevent rotation in high-vibration applications.
How do brass castle nuts differ from 304 stainless steel castle nuts?Brass castle nuts offer moderate corrosion resistance and a decorative gold-like finish for low-corrosion settings, while 304 stainless steel castle nuts provide superior corrosion resistance for outdoor and mildly corrosive environments.
Are brass castle nuts suitable for marine environments?No, brass castle nuts have moderate corrosion resistance and are best for indoor or low-corrosion settings. For marine environments, 316 stainless steel or silicon bronze castle nuts are recommended.
How do I install brass castle nuts?Thread the nut onto the bolt, tighten to align a slot with the bolt’s hole, insert a cotter pin through the slot and hole, and bend the pin’s ends to secure. Avoid over-torquing due to brass’s softer nature.
How do I choose the right size brass castle nut?Select based on the bolt’s thread size, such as 1/4"-20, 3/8"-16, or 1/2"-13. Ensure the nut’s thread pitch matches the bolt and the slot aligns with the bolt’s hole for the cotter pin.
