Adjusting Bolts & Nuts - 4-Pack

The Adjusting Bolts & Nuts - 4-Pack from YELLA TERRA delivers precision fastening hardware purpose-built for tactical firearms, optics mounts, and accessory assembly. Whether you're a gunsmith, armorer, law enforcement technician, or serious competitive shooter, these replacement bolts and nuts address a critical need: secure, repeatable fastening of critical components that demand absolute zero-movement under recoil and field use. Loose hardware compromises zero, sight picture stability, and ultimately mission reliability.

This four-piece set provides redundancy and versatility across multiple applications—mounting rails, adjustable stocks, picatinny accessories, and optic base attachment points all benefit from quality bolts and nuts engineered to standard tolerances. YELLA TERRA fasteners are manufactured to resist vibration-induced loosening, a common failure mode in duty and range environments where repeated firing cycles generate micro-movements. The compact 5 x 1 x 7.5-inch package weighs only 0.145 lbs, making this set ideal for field repair kits, gunsmith benches, and tactical go-bags where space and weight discipline matter.

Professionals who maintain AR-platform rifles, precision optic systems, and modular accessories recognize that hardware failure often goes undiagnosed until critical moment—a loose base screw, a missing accessory fastener, or vibration-loosened mount bolts can degrade accuracy and create safety liability. Keep this 4-pack on your armorer's workbench or in your duty bag for immediate access to verified replacement fasteners. Installation requires only standard tools; compatibility spans most tactical rail systems and universal picatinny-based accessory mounting platforms commonly found in law enforcement and military service rifles.
