一、对小六角自锁螺母GB924—67修订的主要说明 将原小六角自锁螺母GB924—67分为:《六角自锁螺母》GB1337—77,《小六角扁自锁螺母》GB1338—77和《小六角自锁螺母》GB1339—77三个标准。六角自锁螺母—用于承拉和夹层材料强度较低时;小六角扁自锁螺母—用于承剪和拉剪组合中以剪为主;小六角自锁螺母—用于拉剪组合中以拉为主和夹层材料强度较高时。
First, the small hexagonal self-locking nut GB924-67 revised main instructions The original hexagonal self-locking nut GB924-67 is divided into: “hexagonal self-locking nut” GB1337-77, “small hexagonal flat self-locking nut” GB1338-77 and “Small hexagonal self-locking nut” GB1339-77 three standards. Hexagonal self-locking nut - for tensile strength and sandwich material lower strength; small hexagonal flat self-locking nut - used for cutting and shearing combination of shear-based; small hexagonal self-locking nut - used in the combination of tension and shear The main pull and sandwich material when the high intensity.
