Lock It In: A Sparky's Guide to Conduit Locknuts

A conduit fitting is only as secure as the nut that's holding it tight. A loose connection that vibrates over time isn't just unprofessional—it's a future point of failure. The humble electrical locknut is the essential component that guarantees a rock-solid, vibration-proof fastening for your conduit entries into switchboards, junction boxes, and enclosures.

At SCHNAP, our Locknuts range offers Aussie tradies and contractors reliable, top-quality fittings for every electrical setup, from a standard domestic fit-out to the toughest industrial site.

Choosing the Right Locknut Material for the Job

Selecting the right material for the environment is key to a long-lasting, compliant installation.

• Durable Nylon Locknuts: The versatile and cost-effective choice for securing PVC fittings into PVC or plastic enclosures. They are naturally corrosion-free and easy to work with, making them a staple in any sparky's kit.
• Machined Brass Locknuts: The industry standard for a secure mechanical and electrical earth continuity bond. When you're connecting metal conduit fittings to a steel switchboard or enclosure, a brass locknut is the professional's choice. Our range includes Clipsal-compatible gear you can rely on.
• Marine-Grade 316 Stainless Steel Locknuts: For the toughest Aussie conditions, you need the ultimate in corrosion resistance. For installations in coastal, marine, or highly corrosive industrial environments (like food processing plants), 316 stainless steel locknuts offer unparalleled long-term performance and prevent rust.
