BC-M453010HMA M3-0.5X10 4.5 MM Hex Male-Female Standoff, Aluminum (Pack Qty 500)

Male‑female standoffs are designed for assemblies where one part requires an internally threaded spacer. Aluminum versions are widely chosen for a useful compromise of light weight and mechanical strength; they are non‑magnetic, handle extreme temperatures well, and offer some insulating characteristics. Stainless alternatives provide electrical conductivity, excellent resistance to corrosion and chemical fumes, and are non‑magnetic, but they are typically more expensive than aluminum.
