Half Nut 1/2-20 Thread Black 10 Pack

The Half Nut 1/2-20 Thread Black 10 Pack from Ti22 PERFORMANCE delivers professional-grade fastening solutions for high-performance engine builds, transmission work, and precision mechanical assembly. These locking half nuts are engineered for applications where a secure, repeatable connection is critical—particularly in automotive racing, engine rebuilds, and heavy-duty mechanical systems where vibration and thermal cycling demand failsafe retention. The 10-pack format provides an economical solution for technicians, shops, and enthusiasts who require reliable fasteners for multiple projects or assembly stations.

Constructed from hardened steel with black oxide finish, each half nut features a hex head design paired with a nylon insert locking mechanism that prevents loosening under vibration and temperature fluctuation. The 1/2-20 thread specification delivers a fine pitch that enables precise adjustment and superior load distribution compared to standard coarse-pitch fasteners. The nylon insert creates a friction lock without compromising the fastener's reusability—critical for applications requiring multiple assembly and disassembly cycles. Black oxide coating provides corrosion resistance and enhanced durability in engine compartments and other demanding environments.

Half nuts excel in applications where full nuts create packaging or clearance constraints—particularly on threaded rods, pump shafts, and precision adjusters where space is limited. Technicians frequently pair these fasteners with studs and fine-pitch threads in carburetor linkage, fuel system components, and ignition timing adjustments. The locking nylon insert remains effective across repeated use, making this 10-pack ideal for shop environments, restoration projects, and racing teams that standardize on proven fastening components for long-term reliability.
