Flush Hd Fasteners 7/16 .400in 50pk Alum

The Flush HD Fasteners 7/16 .400in 50pk Alum by Allstar Performance delivers precision-engineered quick-turn fasteners designed for high-performance automotive and racing applications. These flush head fasteners are engineered for builders and technicians who demand reliable, lightweight solutions in engine assembly, chassis work, and drivetrain applications. The 50-pack quantity makes this set ideal for shops and serious enthusiasts tackling multiple projects or rebuilds where consistency and speed are essential.

Manufactured from aluminum and finished in black anodize, these 7/16-inch fasteners feature a slotted flush head design that sits flush with mounting surfaces, eliminating protrusions that could interfere with components or airflow. The 0.400-inch body diameter and flush profile reduce weight compared to standard steel fasteners—critical in racing and performance builds where every gram matters. The slotted design allows quick hand-tool installation and removal without requiring specialized bits, while the aluminum construction resists corrosion in harsh engine bay and underbody environments.

Performance builders, race teams, and restoration shops benefit most from this fastener set when securing intake manifolds, valve covers, timing covers, and other engine bay components where weight savings and clean aesthetics matter. The black anodized finish complements modern engine builds while providing mild corrosion resistance. Each fastener is individually sized at 7/16 x 0.400 inch, ensuring compatibility with standard threaded holes in cast aluminum and iron engine blocks, cylinder heads, and accessory housings common to street and race engines.
