A non-threaded insert operable to transfer a mechanical load to a structure, comprising: an upper insert having an axis and an upper head with a noncircular cross sectional shape transverse to the axis, wherein the structure has an upper countersink that is complementary in shape to and receives the upper head of the upper insert to prevent rotation of the upper insert relative to the structure; a lower insert coaxial with the upper insert and having a lower head, wherein the structure has a lower countersink that is complementary in shape to and receives the lower head of the upper insert, and wherein the lower insert couples to the upper insert, such that the coupled upper insert and lower insert are operable to receive a mechanical load and distribute the load to the structure; and a mechanical fastener extending through the lower insert, threadingly engaged to at least the upper insert, and operable to couple to the mechanical load.
