There are differences between combination screws and ordinary bolts in the following aspects:

Structure and appearance: The shape and structure of combination screws and ordinary bolts are different. A combination screw usually consists of a bolt head, a screw, and a nut, while a regular bolt consists of a bolt head and a screw. In addition, the screw of a combination screw is usually thinner than the screw of a regular bolt.

Usage: Combination screws and ordinary bolts have different usage methods. To assemble a screw, first assemble the nut and spring washer or flat washer onto the screw, then insert the assembled screw into the hole and tighten it with a wrench or screwdriver. For ordinary bolts, the bolt head needs to be inserted into the hole and tightened using a wrench or screwdriver.

Combination screw

Tightening effect: The tightening effect of combination screws is usually better than that of ordinary bolts. Due to the fact that the nut and spring washer or flat washer of the combined screw can provide additional friction and pressure during tightening, it can better secure the connection and improve the tightening effect. Ordinary bolts, on the other hand, mainly rely on the frictional force between the bolt head and the connecting piece to secure the connecting piece.

Application range: The application range of combination screws and ordinary bolts is also different. Combination screws are usually used in situations that require high-precision coordination, such as precision machinery, optical instruments, etc., as they can provide more stable and reliable fixation. Ordinary bolts are more commonly used in general mechanical equipment, furniture, construction, and other occasions.

Cost and maintenance: The cost and maintenance of combination screws and ordinary bolts also vary. Combination screws are usually more expensive than ordinary bolts because they require more materials and finer processing. In addition, the maintenance of combination screws is also relatively complex, as if any of the components are damaged, the entire combination screw needs to be replaced. Ordinary bolts are easier to maintain, and if any of the components are damaged, they can be replaced separately.
