Stand Bolt - 7/16-14 x 1.250 12pt

The T AND D MACHINE Stand Bolt – 7/16-14 x 1.250 with 12-point head is a precision fastener engineered for engine rebuild work, particularly rocker arm assembly applications. This steel bolt delivers the exact thread specification and head geometry required for secure, repeatable installation in high-vibration environments where fastener integrity directly impacts engine reliability and performance.

The 7/16-14 thread size provides the fine-pitch engagement necessary for precise torque control during rocker arm assembly, reducing the risk of over-tightening or stripping. The 12-point head design increases contact surface area compared to traditional 6-point heads, distributing load more evenly and minimizing socket slip during installation. At 1.250 inches in length, this bolt bridges the specific gap between rocker arm and mounting surface without requiring shims or spacers, maintaining OEM alignment. The steel construction offers the strength and hardness needed to withstand repeated assembly-disassembly cycles and engine operating vibration without fatigue failure.

Technicians rebuilding small-block and mid-size engines, or those performing valve train maintenance, depend on fasteners with this exact specification to avoid dimensional mismatches that compromise rocker arm geometry. Whether performing a full engine rebuild, addressing a single worn bolt, or stocking parts for a machine shop, this T AND D MACHINE fastener delivers the precision fit that OEM specifications demand. Individual unit pricing makes it easy to order replacements without bulk commitment.

Part number 05220 is the direct replacement for rocker arm assemblies requiring this exact bolt dimension and head configuration. Verify your engine manual to confirm the 7/16-14 x 1.250 specification before ordering.
