Customized THUMB SCREW manufacturers From China | MaiJin Metal

Product introduction

A thumb screw is designed for manual tightening and loosening without the need for tools like screwdrivers or wrenches. It features a tall head with ridged or knurled sides, which gives the user a better grip and torque force when handling hand-installed fasteners and components.

MAIJIN thumb screws are highly regarded in various industries due to their precise dimensions and robust durability.

Types of thumb screws

Type A thumb screws, also known as Type S, feature a shoulder that acts as a bearing surface. This design allows the thumb screw to be securely tightened against the mating surface.

Type B thumb screws, alternatively referred to as Type P, lack a shoulder. These shoulderless thumb screws are commonly utilized as compression fasteners, where the tip makes direct contact with the mating surface.
