1/4-28 HEX NUT (BERT)

The 1/4-28 HEX NUT (BERT) is a precision-engineered fastener designed for demanding tactical, firearms, and industrial applications where reliable thread engagement is non-negotiable. This hex nut serves as a critical component in firearm builds, suppressors, barrel assemblies, and other precision equipment where proper torque retention and vibration resistance are essential. Whether you're assembling an AR platform, installing muzzle devices, or securing critical components in tactical systems, this fastener delivers the consistency professionals demand.

Manufactured from steel with a cadmium plating finish, the 1/4-28 HEX NUT (BERT) provides corrosion resistance and enhanced durability in high-stress environments. The cadmium coating protects against oxidation and extends service life, particularly valuable in field conditions where exposure to moisture and temperature fluctuations occurs. The hex head design allows secure installation with standard wrenches or sockets, enabling consistent torque application without risk of rounding or stripping. At just 0.01 lbs with compact dimensions of 0.5 x 0.25 x 0.5 inches, this fastener minimizes weight while maintaining structural integrity and load-bearing capacity required for precision firearm assemblies.

Armorers, gunsmiths, and tactical equipment builders rely on the 1/4-28 HEX NUT (BERT) for repeatable results across suppressor mounts, barrel extensions, rail systems, and modular firearm platforms. The 1/4-28 thread pitch ensures compatibility with standard precision fastening applications throughout the firearms and defense industries. Sold as a single unit, this nut is ideal for replacement, repair, or complete system builds where matching specifications with existing components is critical. Proper installation requires appropriate torque values specific to your application—consult manufacturer guidelines for your particular assembly to ensure optimal performance and safety.
