Hex Head Bolt 3/4-16 x 6 Grade 5

The Hex Head Bolt 3/4-16 x 6 Grade 5 is a precision-engineered fastener designed for demanding mechanical and tactical applications where reliability under stress is non-negotiable. Manufactured by ALLSTAR PERFORMANCE to Grade 5 specifications, this bolt serves as a critical component in firearm builds, vehicle assembly, load-bearing equipment, and field-maintainable weapon systems where standard hardware fails. Whether you're securing rail systems, mounting optics platforms, or assembling tactical platforms that demand repeatability under sustained use, this fastener provides the structural integrity field operators and gunsmiths depend on.

Engineered with a 3/4-inch diameter and 16 threads per inch, this bolt delivers consistent clamping force and precise torque retention across repeated duty cycles. The 6-inch length accommodates deep-stack assemblies and multi-component mounting scenarios common in modular rifle builds and equipment interfaces. Constructed from Grade 5 steel with zinc oxide coating, the fastener resists corrosion while maintaining tensile strength rated at 120,000 PSI—essential for applications involving recoil transfer and load cycling. The 1-1/8 inch hex head accepts standard wrench and socket sizes for field installation without specialized tools, enabling rapid maintenance and component swap in austere environments.

This fastener is ideal for armorer-level builds, vehicle platform assembly, and equipment manufacturers requiring universal compatibility across multiple mounting interfaces. Law enforcement and military units leverage Grade 5 hardware for mission-critical applications where fastener failure creates liability or operational risk. Installation requires standard wrenching—torque specifications vary by application, but 3/4-16 bolts typically range 150–220 foot-pounds depending on interface material and load direction. Stock this fastener for equipment maintenance, spare-parts inventories, and field-level repairs where standardized hardware ensures interoperability across tactical platforms.
