Buy Socket Screws Online at South Coast Fasteners

Socket screws are essential fasteners known for their strength, precision, and versatility across a wide range of industries. Whether you need to secure heavy machinery, assemble electronics, or build structural components, socket screws offer reliable performance with clean installs. Below is a breakdown of the common socket screw types we carry and their key applications.

Types of Socket Screws

Socket Head Cap Screws

Socket head cap screws are the go-to in high-torque and low-clearance applications where strength is needed. Designed with a cylindrical head and internal hex socket, theyre easy to install with a Standard Allen key. These are used everywhere from heavy machinery to automotive lines and aerospace assemblies.

Flat Socket Cap

Flat socket caps are designed to sit flush with the surface; it's a top pick in builds where aesthetics matter or where protruding hardware isn't acceptable. Theyre commonly used in electronics, machinery assemblies, and anywhere a clean finish is necessary.

Button Socket Cap

Button socket caps feature a rounded, low-profile head with a hex socket drive. They're usually the choice for visible applications such as furniture, equipment panels, or automotive interiors.

Low Head Socket Cap

Low head socket caps offer the same strength as Standard socket cap screws with a slimmer head height. Perfect for low-clearance installs in electronics, compact machinery, or tight engine compartments.

Socket Shoulder Cap Screws

Socket shoulder cap screws, also known as shoulder bolts, have a machined shoulder between the head and the threaded portion. They're made for rotating or sliding applications and used in moving parts, pivot points, and alignment fixtures.

Pipe Plugs

Pipe plugs are utilized in sealing off the ends of piping systems. With tapered threads and grip, theyre the preferred choice in hydraulic, pneumatic, and plumbing systems. These keep systems leak-free and running tight in industrial and maintenance settings.

Cup Point Set Screws

Cup point set screws have a cup-shaped indentation (cup point) on the end opposite the head. The cup point digs into the mating surface when tightened and provides a secure hold. Most often utilized in machinery, automotive, and equipment assembly for securing components onto shafts without causing any 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 used as an advantage in applications such as fixtures, machinery, and equipment assembly. It prevents tampering, ensuring security in any setting.

Dog Set Screws

Dog set screws have a flat, long tip instead of a pointed or cup-shaped end. They are used in gear and pulley assemblies and provide a strong grip on shafts without causing any surface damage. It is widely used in machinery and automotive industries.

Flat Point Set Screws

Flat point 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 utilized in machinery, equipment, and woodworking applications where a flush surface is required.

Nylon Tip Set Screws

Set screws with a nylon tip at the end, which provides a non-marring, vibration-Resistant grip. They are most commonly used in applications that protect delicate surfaces in furniture assembly, machinery, and electronics applications, preventing damage.

Brass Tip Set Screws

Similar to nylon tip set screws, but with a brass tip. Brass tip set screws offer similar benefits while providing differing aesthetic and material compatibilities. By offering corrosion Resistant and electrical conductivity, these screws are the preferred choice in electronics, marine & offshore, and automotive industries where non-ferrous materials are necessary.

Knurled Cup Set Screws

Knurled cup set screws feature a textured inner cup for extra bite. The knurled surface helps grip softer materials or parts that may see movement, offering strong hold. They are utilized in applications allowing for hand tightening without the need for additional tools, usually in automotive and equipment assembly.

Slotted Set Screws

Set screws with a slot on the top of the head, which are compatible for tightening with a flat screwdriver. They are used in applications where 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. These screws are commonly used in heavy machinery, construction, and infrastructure projects where robust fasteners are required.

Socket Screws - Industry Applications

At South Coast Fasteners, we're proud our inventory serves as performance benchmarks across every industry. Have you ever noticed socket screws show up in every corner of every industry? That's because they work. In industrial machinery and equipment, they keep moving parts locked in place. In automotive and aerospace, theyre trusted for high-performance and high-pressure connections. Construction professionals use them for structural integrity, while electronics engineers utilize their low profiles and clean installs. Furniture makers, fixture builders, and even stage designers turn to socket screws when strength and aesthetics matter. Their flush fit keeps surfaces clean and their tamper-Resistant options protect things that actually matter.

Socket Screws - Material and Grades

Socket screws come in various grades, each offering specific properties and characteristics to suit different uses. When selecting the appropriate grade for your application, please consider factors such as required strength, corrosion Resistant, and environmental conditions.

Alloy Steel

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

Stainless Steel

Stainless steel socket screws offer corrosion Resistant, making them ideal for applications exposed to moisture, chemicals, or high temperatures. Common stainless-steel grades used for socket screws include 18-8 (Type 304 & 316) stainless steel, each offering different levels of corrosion Resistant and strength.

Silicon Bronze

Our silicon bronze socket screws deliver superior corrosion Resistant without the red brass content, making them the top choice for coastal city yards and municipal jobs where durability against salt air and moisture is non-negotiable.

Brass

Brass socket screws provide corrosion Resistant, electrical conductivity, and are aesthetically pleasing. They are commonly used in electrical, plumbing, and decorative applications where appearance and conductivity are imporPant.
