Dowel - Solid (1pk) .2466 Dia x .630 Long

The Dowel – Solid (1pk) .2466 Dia x .630 Long is a precision cylinder head dowel engineered for critical engine assembly work. Dowels are essential alignment pins that maintain concentricity between cylinder head and block during fastening, preventing lateral movement that could compromise gasket sealing and bolt load distribution. This single-pack dowel serves as a direct replacement or spare for engine rebuilds, machine shop inventory, or OEM repair applications where exact dimensional tolerance is non-negotiable.

Manufactured from solid steel with a natural finish, this DURA-BOND dowel measures 0.2466 inches in diameter and 0.630 inches in length—dimensions that meet stringent automotive and small engine specifications. Steel construction provides the rigidity and wear resistance required to withstand repeated assembly and disassembly cycles without deformation. The tight tolerance on both diameter and length ensures that the dowel seats firmly in its bore, maintaining alignment throughout engine operation and resisting lateral shear forces common during high-rpm combustion cycles.

Engine builders, machine shops, and powersports technicians rely on precision dowels for four-stroke, two-stroke, and automotive applications where head gasket integrity depends on perfect alignment. Installation is straightforward: the dowel is pressed into the cylinder block dowel hole and accepts the corresponding hole in the cylinder head. Because dowels are often lost, damaged, or worn during disassembly, keeping replacement stock on hand prevents project delays. The compact 0.01 lb weight and small footprint make this dowel ideal for emergency kits, repair benches, or complete engine rebuild sets.
