Aluminum Spacers 1/2in ID x 1/4in Long

The ALLSTAR PERFORMANCE Aluminum Spacers 1/2in ID x 1/4in Long (ALL18762) are precision-engineered flat spacers designed for applications requiring accurate standoff spacing and alignment in mechanical assemblies. Constructed from lightweight aluminum and offered as a pair, these spacers deliver consistent dimensional accuracy across high-tolerance mounting scenarios where frame-to-component clearance or layup spacing demands precision.

Each spacer measures 1/2 inch inner diameter by 1 inch outer diameter with 1/4 inch thickness, providing a standardized footprint compatible with common fastener hardware and mounting rails. The aluminum construction offers an optimal balance of weight reduction and dimensional stability—critical for applications where part creep or deflection under load can compromise alignment. Natural finish aluminum resists corrosion in standard indoor and moderate environmental conditions, while remaining easy to machine or drill if secondary customization is required during installation.

Technicians, gunsmiths, engineers, and fabricators rely on spacer sets like these for precision rifle builds, optics mounting systems, rail standoff applications, and component layup work. The 1/4 inch thickness accommodates medium-load spacing where thinner shims would flex, while the 1/2 inch bore accepts standard 1/2 inch bolts, screws, and fastening hardware. Pair quantity allows matched installation on dual-rail systems or complementary assemblies.

ALLSTAR PERFORMANCE spacers meet the expectations of users who demand consistency and reliable dimensional accuracy across assembly work. Stock this pair as a foundational spacer size for shop inventory or include them in precision build kits where standoff spacing is non-negotiable.
