Chenango Supply 1/2-13 Grade 8 Nylon Insert Lock Nuts – Alloy Steel, Yellow Zinc Chromate, USS Coarse Thread Nylock Hex Nuts, High-Strength Fastening, 50 Pieces (1/2-13 Nylock)

Grade 8 nylon insert lock nuts engineered for high-strength fastening applications where vibration resistance, load retention, and dependable thread engagement are required. Specifications Nut type: Nylon insert lock nut (Nylock) Thread size: 1/2-13 Thread type: USS coarse thread Grade: Grade 8 Material: Quenched and tempered alloy steel Minimum tensile strength: 150,000 PSI Finish: Yellow chromate zinc coating Quantity: 50 pieces Performance & Application Explanation Grade 8 Nylock nuts combine hardened alloy steel strength with a nylon insert that resists loosening caused by vibration or movement. The 1/2-13 USS coarse thread provides dependable engagement with matching fasteners, while the nylon insert increases friction on the threads to maintain clamp load over time. This design is well suited for high-stress assemblies where standard hex nuts may loosen during service. The yellow chromate zinc coating adds corrosion resistance and allows quick visual identification of Grade 8 hardware during installation and inspection. B2B Use Cases Commonly used in heavy machinery, automotive repair, equipment fabrication, agricultural machinery, and industrial maintenance applications where high-strength, vibration-resistant fastening is required. Quality & Trust Reassurance Manufactured from hardened alloy steel with verified tensile strength and consistent threading to meet professional expectations. Designed for mechanics, fabricators, and maintenance teams who rely on Grade 8 locking hardware for critical fastening performance in demanding environments.

• GRADE 8 HARDENED ALLOY STEEL CONSTRUCTION – Manufactured from quenched and tempered alloy steel to deliver high-strength fastening performance for demanding mechanical, automotive, and industrial applications.
• ENGINEERED HIGH-STRENGTH PERFORMANCE – Rated with a minimum tensile strength of 150,000 PSI, supporting secure clamping and resistance to loosening in high-load environments.
• 1/2-13 USS COARSE THREAD NYLOCK DESIGN – 1/2-13 coarse thread provides reliable engagement with standard USS bolts, while the nylon insert locks onto the fastener to resist vibration-induced backing off.
