A breakaway bolt (10) formed from a shaft (12) having a first end (14), a second end (16), and a breakaway shank (18). The breakaway segment is formed from laterally projecting and circumscribing flanges (22 and 24) that reduce in diameter to form cones (26 and 28) that intersect at a midpoint intersection (30) to create a preformed stress point that will break when the first end (14) or second end (16) is subjected to a predetermined lateral load. A breakaway spacer (32) formed in accordance with the present invention form a shaft (34) to have a first end (36) and a second end (38) that are connected by a breakaway shank (40). A first flange (44) and second flange (46) project laterally outward from and circumscribe the shaft (34) to form shoulders (48 and 50) and cones (52 and 54) that intersect at a midpoint intersection (56) to form a preformed stress point that allows the spacer (32) to break in any direction when subjected to a predetermined lateral load.
