Features

• 50Pcs Value Pack 1/4"-20 Lock Nuts: this 50 pack includes 1/4"-20 UNC Stainless Steel Low Profile Jam Locknuts (20 TPI) with precise threads for smooth engagement; Ideal for large boat repairs, automotive maintenance, or home DIY projects, they fit most standard 1/4-inch bolts perfectly, ensuring you have enough fasteners for multiple tasks
• 304 Stainless Steel with Black Oxide Finish: made of quality 304 stainless steel, these lock nuts feature a durable black oxide surface treatment that enhances both texture and wear resistance; They offer excellent mechanical strength and toughness, resisting stripping and breakage, with rust, oxidation, and corrosion resistance for reliable performance even in humid, outdoor, or marine environments
• Anti-loose Nylon Insert Design: each nut is equipped with a nylon insert that creates continuous friction with the bolt threads when tightened; This effectively prevents loosening caused by vibration, impact, or temperature changes, ensuring stable connections in equipment operation and high-frequency use scenarios
