M4-0.7x12 6 mm Hex Male-Female Standoff, Aluminum (Pack Qty 500) BC-M604012HMA

Male-female standoffs are used when one mating part contains internal threads; the male end screws into that component while the female end accepts a mating screw. Aluminum options are chosen for their balance of low weight and strength, with non-magnetic behavior, good performance in extreme temperatures, and some insulating characteristics. Stainless steel alternatives are conductive, non-magnetic, offer superior resistance to corrosion and chemical fumes, and are more expensive than aluminum.
