BC-M452506HMA M2.5-0.45X6 Hex Male-Female Standoff, 4.5 MM Aluminum (Pack Qty 500)

Use male–female standoffs when one mating component contains internal threads. They provide a secure threaded spacer solution for assemblies. Aluminum is commonly chosen for standoffs because it balances light weight with adequate strength. It is non-magnetic, tolerates extreme temperatures, and offers insulating characteristics. By contrast, stainless steel delivers better corrosion and chemical fume resistance, remains non-magnetic, and is electrically conductive; stainless options are typically more expensive than aluminum.
