Reducer Spacers 5/8 to 1/2 x 1/2 Steel 20pk

The ALLSTAR PERFORMANCE Reducer Spacers 5/8 to 1/2 x 1/2 Steel 20-pack (SKU ALL18612-20) provides precision-engineered spacer components for high-performance machinery assembly. These zinc-plated steel reducer spacers bridge diameter transitions from 5/8 inch outer diameter to 1/2 inch inner diameter with a 1/2 inch thickness, making them essential fastening solutions for automotive, industrial, and motorsports applications where dimensional accuracy and corrosion resistance matter.

Each spacer is manufactured from steel and zinc-plated to resist oxidation in both dry shop and humid environments. The 1/2 inch thickness provides adequate load distribution for structural fastening applications, while the precise diameter reduction accommodates standard fastener sizing across equipment assemblies. The set of 20 individual spacers delivers sufficient inventory for prototyping, repair, and production runs without requiring frequent reorders. Zinc plating delivers corrosion protection suitable for long-term indoor storage and short-term outdoor exposure.

These reducer spacers are specified in engine block assembly, transmission mount fabrication, and chassis reinforcement projects where bolt-hole alignment requires step-down sizing. Fabricators, restoration shops, and motorsports technicians stock these spacers to accommodate mismatched bolt patterns and fastener sizing across vintage and modern equipment. The bulk 20-pack format reduces per-unit cost for shops managing multiple builds or high-volume production environments where spacer consumption is consistent.

TacticalSurplusUSA stocks ALLSTAR PERFORMANCE fastening components for builders, fabricators, and technicians who require OEM-compatible hardware with verified material specifications. These zinc-plated steel reducer spacers integrate into existing fastening systems without modification and are compatible with standard SAE bolt diameters and torque specifications.
