5/8 UNF 2.1/2 BOLT (WATTS LINK INNER & LH LOWER)

Hex Bolt 5/8" UNF x 2-1/2" Grade 8 Zinc Plated

Engineered for demanding suspension and chassis applications, this 5/8" UNF Grade 8 hex bolt is commonly used in Watts link assemblies where strength, precision and reliability are critical. The fine-thread UNF design provides increased clamping force and improved resistance to loosening under vibration, making it ideal for motorsport environments.

Manufactured from high-tensile Grade 8 steel and finished with a zinc-plated coating, this bolt offers excellent durability and corrosion resistance. The partially threaded shank allows loads to be carried through the solid section of the bolt, improving shear strength in suspension mounting applications.

Commonly used as a Watts link inner mounting bolt and left-hand lower Watts link fastener on TA2 and Trans Am race cars, as well as other high-performance suspension systems.
