Oval Hd T-30 Torx Fast. 7/16 .550in 50pk Alum Bl

The Oval Head T-30 Torx Fast fastener from ALLSTAR PERFORMANCE is purpose-built for high-performance automotive applications where precision fastening and repeatable clamp load are non-negotiable. Sized at 7/16 x 0.550 inches, this fastener is engineered for engine bay work, transmission assembly, and structural modifications where vibration resistance and torque reliability matter. Mechanics and fabricators trust this 50-pack aluminum specification for builds ranging from naturally aspirated street engines to forced-induction platforms that demand exacting fastener geometry.

The oval head design distributes clamping force across a wider footprint than standard fasteners, reducing point loading on soft materials and composite surfaces common in modern engine covers, intake manifolds, and timing covers. The T-30 Torx geometry—with its six-point star profile—eliminates cam-out risk during installation and removal, a critical advantage when working in tight engine compartments where socket alignment is compromised. Aluminum construction keeps overall weight low, important for motorsports applications where unsprung mass impacts suspension geometry and fuel economy, while maintaining corrosion resistance in underhood environments.

This fastener excels in engine bay assembly, intake manifold installation, accessory bracket mounting, and any structural fastening where conventional Phillips or slotted heads would strip or fail under thermal cycling. The 50-pack quantity supports both full engine builds and ongoing restoration work, eliminating repeated shop runs for replacements. Compatible with standard T-30 Torx tools, these fasteners integrate seamlessly into professional and home shop environments, delivering the precision fit and holding power that separates reliable builds from chronic vibration issues and fastener failure.
