Socket Head Cap Screws: These screws have a cylindrical head with a hexagonal recess (socket) for tightening with an Allen key or hex key. They are commonly used in applications where a strong, flush connection is required. Widely used in machinery and equipment assembly, automotive manufacturing, aerospace engineering, and electronics industries for strong and low-profile fastening.

Flat Socket Cap: In similarity to socket head cap screws, but with a flat top surface instead of a rounded one. This design allows for a flush fit when tightened, making them suitable for applications where protruding fasteners are undesirable. Commonly employed in automotive, machinery, and electronics applications where a flush surface is essential for proper assembly and aesthetics.

Button Socket Cap: These screws feature a rounded, dome-shaped head with a recessed hexagonal socket. Found in equipment assembly, furniture manufacturing, and automotive industries where a rounded, domed head provides a visually appealing and secure fastening solution. They are often used in decorative or aesthetic applications.

Low Head Socket Cap: Also known as low-profile socket head cap screws, these fasteners have a reduced head height compared to standard socket head cap screws. Utilized in applications with limited clearance requirements or lower profile settings are preferred, such as machinery and equipment assembly, automotive, and electronics.

Socket Shoulder Cap Screws: These screws have a cylindrical head with an integral shoulder between the head and the threaded portion. They are commonly found in rotating or sliding applications where precise alignment and positioning are critical, commonly used in machinery, tooling, and automotive industries.

Pipe Plugs: Pipe plugs are used to close off the ends of pipes or fittings. They typically have a tapered thread design to create a tight seal when installed. They are essential components in plumbing, hydraulic, and pneumatic systems, used to seal or close the end of pipes or fittings in various industries, including construction, manufacturing, and maintenance.

Cup Point Set Screws: These screws have a cup-shaped indentation (cup point) on the end opposite the head. The cup point digs into the mating surface when tightened, providing a secure hold. They are often employed in machinery, automotive, and equipment assembly for securing rotating components onto shafts without causing damage.

Oval Point Set Screws: Similar to cup point set screws, but with an oval-shaped indentation on the end. Oval point set screws offer a slightly different contact surface, which may be advantageous in certain applications such as fixtures, machinery, and equipment assembly as this will prevent tampering or unauthorized adjustments, ensuring security in various industrial settings.

Dog Set Screws: Dog set screws have a flat, elongated tip instead of a pointed or cup-shaped end. They are commonly found in gear and pulley assemblies, providing a strong grip on shafts without causing extensive surface damage, widely used in machinery and automotive industries.

Flat Point Set Screws: These set screws have a flat tip at the end, providing a larger contact surface area compared to cup or oval point set screws. They are often utilized in machinery, equipment, and woodworking applications where a flush surface is required to maintain proper alignment and functionality.

Nylon Tip Set Screws: Set screws with a nylon tip at the end, which provides a non-marring, vibration-resistant grip when tightened. They are commonly used in applications in protecting delicate surfaces in furniture assembly, machinery, and electronics applications, providing a non-marring grip and preventing damage.

Brass Tip Set Screws: In similarity to nylon tip set screws, but with a brass tip. Brass tip set screws offer similar benefits of non-marring grip while providing a different aesthetic or material compatibility. Offering corrosion resistance and electrical conductivity, these screws are often used in electronics, marine, and automotive industries where non-ferrous materials are preferred.

Knurled Cup Set Screws: These set screws have a knurled surface on the cup-shaped indentation, providing enhanced grip when tightened. Handy in adjustable components and machinery, they are utilized in applications allowing for hand tightening without the need for additional tools, commonly found in automotive and equipment assembly.

Slotted Set Screws: Set screws with a slot on the top of the head, allowing for tightening with a flat-blade screwdriver. They are commonly used in applications where access for using a hex key or wrench is limited.

Square Head Set Screws: These set screws have a square-shaped head instead of a hexagonal or slotted head. Square head set screws are often used in heavy-duty applications where higher torque is required for tightening. These screws are commonly used in heavy machinery, construction, and infrastructure projects where robust fastening solutions are necessary.

Applications and Amenities

Socket screws serve as indispensable amenities across a spectrum of industries, ensuring robust and reliable fastening solutions. In machinery and equipment assembly, they provide steadfast support, while the automotive and aerospace sectors rely on their durability for critical components. Within construction and structural engineering, socket screws offer steadfast anchoring, while the electronics and electrical enclosures industry benefits from their secure installations. Moreover, in furniture assembly and woodworking, socket screws deliver precise and sturdy connections. Their advantages are manifold, including high strength and durability, contributing to the resilience required in these demanding fields. Additionally, their flush installation ensures a sleek and professional appearance, while their resistance to tampering safeguards sensitive equipment. With the ability to withstand high torque applications, they are indispensable in ensuring structural integrity. Furthermore, their ease of installation and removal using common hand tools streamlines operations across diverse industries.
 

Material and Grades

Socket screws come in various grades, each offering specific properties and characteristics to suit different applications. When selecting the appropriate grade for your application, consider factors such as required strength, corrosion resistance, and environmental conditions. We offer a wide range of socket screws in various grades to meet the diverse needs of our customers across different industries.
 
Grade 2: Grade 2 socket screws are the most basic grade and are made from low or medium carbon steel. They are not heat-treated, making them suitable for general-purpose applications where high strength is not required.

Grade 5: Grade 5 socket screws are made from medium carbon steel and are quenched and tempered to achieve higher strength and hardness. They are commonly used in automotive, machinery, and equipment assembly applications where moderate strength and reliability are required.

Grade 8: Grade 8 socket screws are the highest grade of standard socket screws, offering exceptional strength and durability. They are made from medium carbon alloy steel and are heat-treated to achieve their high strength. Grade 8 socket screws are commonly used in heavy machinery, automotive, and structural applications where maximum strength and reliability are critical.

Stainless Steel: Stainless steel socket screws offer excellent corrosion resistance and durability, making them ideal for applications where exposure to moisture, chemicals, or high temperatures is a concern. Common stainless-steel grades used for socket screws include 18-8 (Type 304), 316, and 17-4 PH stainless steel, each offering varying levels of corrosion resistance and strength.

Brass: Brass socket screws provide good corrosion resistance, electrical conductivity, and aesthetic appeal. They are commonly used in electrical, plumbing, and decorative applications where appearance and conductivity are important.

Alloy Steel: Alloy steel socket screws are made from alloy steel containing additional alloying elements such as chromium, molybdenum, or vanadium to enhance strength, hardness, and wear resistance. They are commonly used in high-stress applications such as aerospace, automotive, and machinery.
