S-94830A545 1/2"-13 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance with Flex-Top locking technology that maintains clamp force under dynamic loads
• Enhanced corrosion protection through cadmium-plated steel construction for extended service life in harsh environments
• Space-saving thin profile (21/64" height) ideal for applications with limited clearance while maintaining full locking performance
• Reliable thread engagement with Class 2B thread fit ensuring consistent installation and removal without galling
• Easy installation and removal using standard wrenches thanks to the external hex drive design
• Optimized for high-volume assembly with coarse UNC threads that speed up installation while reducing cross-threading risks
• Durable locking performance that withstands repeated use without compromising vibration resistance

Professional Applications & Engineering Value

This 1/2"-13 UNC thin Flex-Top locknut delivers critical vibration resistance in demanding industrial environments where constant motion and shock loads threaten fastener integrity. The cadmium-plated steel construction provides essential corrosion protection for outdoor equipment, agricultural machinery, and transportation applications exposed to moisture and chemicals. The innovative Flex-Top locking mechanism creates consistent radial pressure along the thread engagement, eliminating the need for additional locking components while maintaining reliable clamp force. With its thin profile and external hex drive, this locknut solves space-constrained fastening challenges in assembly lines, heavy equipment maintenance, and structural frameworks where accessibility is limited. The coarse UNC thread specification ensures quick installation and superior resistance to vibration-induced loosening in high-cycle applications.

Specification Summary & Compliance

This locknut features precision Class 2B thread fit with 1/2"-13 UNC coarse threads and right-hand thread direction, manufactured to industry standards for consistent performance. The external hex drive measures 3/4" across flats with a total height of 21/64", maintaining dimensional accuracy for reliable tool engagement. The cadmium-plated steel construction complies with industrial fastener specifications and provides enhanced corrosion resistance. Manufactured to meet relevant industrial standards for locknuts, this product is suitable for applications requiring reliable vibration-resistant fastening solutions.
