The Adjuster - 5/16 Dia. Cup - 7/16-20 Thread by T AND D MACHINE is a precision-engineered fastening component designed for high-performance engine builds and valve train modifications. This adjuster serves as a critical link in rocker arm assemblies, allowing mechanics and engine builders to fine-tune valve clearance and optimize valve timing geometry.
Manufactured to strict tolerances, the 5/16-inch diameter cup provides a stable seating surface for rocker arm contact while the 7/16-20 thread specification ensures secure installation and minimal risk of loosening under engine vibration. The overall length of 5.25 inches and a cup width of 0.5 inches make it suitable for various engine bay environments without sacrificing adjustability.
This adjuster is ideal for small-block and mid-sized engine platforms using rocker arm assemblies with corresponding cup geometry. Technicians rebuilding classic muscle cars, hot rods, or modern performance engines frequently specify T AND D MACHINE products for their commitment to material quality and dimensional accuracy, which are critical for optimal engine performance.
