Reducer bolts, also known as transfer size head screws, are specialized fasteners designed to join components with different thread sizes or diameters. These bolts feature a head that is larger than the shaft, allowing for a secure connection between mismatched parts. They are commonly used in applications where a transition between different sizes or types of threads is required .

Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.

Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.

Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.

Advantage:

Size Transition: They allow for the connection of components with different thread sizes, facilitating the assembly of diverse parts .Versatility: They can be used in a variety of applications, including machinery, equipment, and furniture assembly .Corrosion Resistance: Often made from stainless steel (304/316), these screws offer excellent resistance to rust and corrosion, making them suitable for outdoor use or in humid environments .Easy Installation: The larger head size allows for easier installation with a wrench or socket .Aesthetics: The larger head provides a clean and finished look that is suitable for both functional and aesthetic applications .

Scope of 

Application

Machinery and Equipment: Used in machinery frames and equipment where a secure and adjustable connection is needed between components of different sizes .Construction: Employed in building structures where a secure connection is required between components of varying sizes .Automotive Industry: Used in the assembly of vehicles where a secure and aesthetically pleasing connection is needed between parts of different sizes .Electronics: Ideal for electronics where tool-less adjustments are needed between components with different thread sizes .DIY Projects: Popular for DIY projects where a secure connection between mismatched parts is required .
