Economical 5PCS: Includes 5 industrial-grade spacers (1/2" Bore x 1" OD x 2" Length) - perfect for medium-scale projects with cost savings over single units.
Reinforced Steel Construction: Zinc-plated Q235 carbon steel provides 2X load capacity vs aluminum, with corrosion resistance for outdoor/industrial use.
Extended Length Design: 2" height creates optimal spacing for heavy machinery, vehicle suspensions, and structural bracing with vibration dampening.
Precision Compatibility: 1/2" bore (±0.02mm tolerance) fits standard 1/2" (12.7mm) or M12 fasteners; 1" OD ensures stability in high-torque applications.
Tool-Free Assembly: Plain finish unthreaded bushing slides directly onto bolts for 10-second installation - ideal for construction sites and field repairs.
