BRASS SLOTTED NUTS

Product Description

Brass Slotted Nuts

A Brass Slotted Nut (also known as a Castellated Nut) is a hexagonal nut with specialized slots or "notches" machined into the top. This design is specifically engineered for safety-critical applications where it is essential to prevent the nut from backing off or loosening, even under extreme vibration or rotational force.

The Positive Locking Mechanism

The slotted nut works in tandem with a clevis pin or cotter pin. To secure the fastener:

1. The nut is tightened onto a bolt that has a pre-drilled hole in its shank.

2. Once tightened, the slots in the nut are aligned with the hole in the bolt.

3. A cotter pin is inserted through the slots and the hole, and its ends are bent outward.

4. Result: The nut is physically "locked" to the bolt. It cannot rotate or vibrate loose until the pin is manually removed.

Why Choose Brass for Slotted Nuts?

While steel slotted nuts are common in heavy automotive use, Brass Slotted Nuts are preferred for specialized industrial sectors:

• Anti-Galling Properties: In applications that require frequent safety inspections and disassembly, brass provides a "smooth" thread action. It prevents the nut from seizing to the bolt, which is common with stainless steel hardware.

• Corrosion Resistance: Ideal for marine steering systems, aircraft fuel components, and outdoor mechanical linkages where moisture would cause steel pins and nuts to rust together.

• Non-Magnetic: Critical for use in sensitive military, aerospace, and medical instrumentation where magnetic interference must be minimized.

• Spark Resistance: Often used in oil and gas refineries or chemical processing plants where a mechanical spark could be hazardous.

Common Industrial Applications

• Aerospace & Marine: Securing control linkages and propeller shafts where fastener failure is not an option.

• Automotive Restoration: Used in wheel bearings and suspension joints for classic cars to maintain an authentic look with superior corrosion protection.

• Precision Machinery: Locking adjustment screws in place on calibrated industrial equipment.

• Agricultural Equipment: Securing moving parts in harvesters and tractors that are exposed to constant debris and moisture.
