Oval Head Quick Fastener 5/16 x .400

The MOROSO Oval Head Quick Fastener 5/16 x .400 is a slotted aluminum fastening solution engineered for rapid assembly and disassembly in high-stress applications. This set of 10 quick-turn fasteners features an oval head design that provides excellent grip surface while maintaining a low-profile footprint, making them ideal for equipment builds, modular systems, and field repairs where speed and reliability are non-negotiable. The natural aluminum construction delivers corrosion resistance without added weight, a critical consideration for portable tactical systems.

Each fastener measures 5/16 inch in diameter with a .400-inch body length, engineered to mate with standard quarter-inch threaded holes common in modular gear platforms and equipment frames. The slotted head accepts any standard flathead driver, eliminating dependency on specialized tools—critical when operating in austere environments or during rapid field assembly. The 0.07-pound per-unit weight keeps system load minimal, while the compact footprint preserves sight lines and reduces snag hazards on tactical platforms.

Operators, armorer teams, and equipment technicians rely on quick fasteners to reconfigure modular attachment systems without downtime. This MOROSO set serves platform builders, rail-mounted accessory installers, and field-maintenance personnel who need dependable hardware that won't loosen under vibration or repeated assembly cycles. The aluminum construction resists salt-air degradation, making these fasteners suitable for both stateside and expeditionary deployments.

Quick-turn fasteners occupy a specialized niche in tactical hardware—they prioritize speed and accessibility over permanent installation security. Unlike standard socket-head fasteners, the oval-head slotted design trades some torque-locking geometry for immediate accessibility with minimal tools, a tradeoff that makes sense for modular systems where components rotate on and off the platform frequently.
