When it comes to industrial fastening, strength, durability, and precision matter. From large-scale infrastructure projects in New York to manufacturing plants in New Jersey and construction zones across Chicago, choosing the right type of fastener can make a big difference. At G-Fast, we proudly supply USA-made fasteners to the entire country, delivering quality and consistency that professionals trust.
In this blog, we’ll break down the key differences between hex head cap screws, socket cap screws, button head socket cap screws, flat head socket cap screws, metric flange screws, and hexagon head cap screws. Whether you’re sourcing fasteners for heavy equipment or custom machinery, this guide will help you find the right screw for your application.
Understanding Hex Head Cap Screws
Hex head cap screws are among the most commonly used fasteners in construction and heavy-duty applications. Designed with a six-sided head, these screws offer strong torque capabilities when tightened using a wrench or socket. Their uniform threading and precise dimensions make them suitable for high-stress environments.
Applications of Hex Head Cap Screws:
-
Machinery assembly
-
Bridge and infrastructure construction
-
Industrial repair projects
At G-Fast, our hex head cap screws are manufactured to meet ASTM standards, ensuring performance and safety.
Socket Head Cap Screws: Compact and Strong
Socket head cap screws have a cylindrical head and internal hex drive, allowing them to be tightened with an Allen wrench. They are ideal for applications where space is limited or where the screw head needs to sit flush or below the surface of the material.
Benefits:
-
High tensile strength
-
Ideal for high-load applications
-
Cleaner aesthetic in visible applications
We offer both inch and metric socket head cap screws for clients across the USA, including contractors in New York, New Jersey, and Chicago.
Button Head Socket Cap Screws: Low-Profile Versatility
For applications where a sleek, low-profile head is required, button head socket cap screws are an excellent choice. Though they offer less torque capacity than socket head styles, they are perfect for lighter-duty assemblies and present a smooth, finished look.
Common uses:
-
Electronic enclosures
-
Furniture assembly
-
Automotive trim components
These screws are a favorite among designers and engineers seeking functionality with a polished appearance.
Flat Head Socket Cap Screws: Flush Mounting Solutions
Flat head socket cap screws are ideal when a flush surface is needed. They’re often used in countersunk holes where a protruding head would interfere with moving parts or aesthetics.
Advantages:
-
Sits flush with the surface
-
Provides clean, professional finishes
-
Internal hex drive for easy installation
Our USA-made flat head socket cap screws are available in alloy steel and stainless steel options for corrosion resistance and long-term durability.
Metric Flange Screws: Built-In Washer Strength
Metric flange screws feature an integrated washer beneath the head. This design spreads the clamping force over a wider area, reducing the risk of damage to softer materials and offering enhanced vibration resistance.
Use cases:
-
Automotive and truck assemblies
-
Equipment maintenance
-
Metal fabrication
With rising demand in industrial sectors from Chicago to the coasts, flange screws offer a smart and efficient alternative to standard bolts.
Hexagon Head Cap Screws: Precision Engineering for Performance
Similar to standard hex bolts, hexagon head cap screws are often used in heavy-duty assemblies. The key difference lies in their tighter tolerances and cleaner finishes, often required in high-spec machinery or structural applications.
