Flat Socket Cap Screws

Socket cap screws are essential to a number of projects and manufacturing processes, and it’s often a good idea to have a wide range of socket cap screws available at all times. While the socket cap screw category is broad, you’ll find a number of ways to winnow down the category to more specific products.

You can choose from among a number of different socket cap screw head options, including flat socket cap screws. You can find flat socket cap screws made from a wide range of materials, too.

At FMW Fasteners, we carry all of the socket cap screws you’ll need, including a number of different flat socket cap screws. Read on to learn more about your different head and material options as well as a few of the common uses for flat socket cap screws.

Different Head Types

As mentioned, not all socket cap screws are the same. Here’s a look at your five most commonly used head options:

Socket Head Cap Screws: These types of screws feature a head height equivalent to the shank’s diameter. This is the strongest of all the head types you’ll find in socket cap screws, but it can’t be used with a traditional hex nut because the attachment won’t be strong enough.

Low Head Cap Screws: On low head cap screws, the head’s height is only about half the shank’s diameter. You see low head cap screws used most often in places where the user is experiencing head height limitations.

Flat Head Cap Screws: When you need to drive a socket cap screw in flush, choose flat head cap screws. You’ll find a variety of countersink angles depending on whether you’re using standard or metric measurements, but beware that installing a fastener with a countersink angle that does not match the angle of the hole can lead to fastener failure far sooner than normal.

Button Head Cap Screws: Perfect for fastening thin materials and for tamper-proof applications, the button head cap screws features a much larger head diameter. It’s also a good replacement if you’ve tried slotted or Phillips fasteners that continually strip during installation.

Socket Shoulder Screws: The shoulders of this type of screws are ground for tight tolerance, which means these screws are perfect for pivot points and axles.

Uses for Flat Socket Cap Screws

Where do you most often find flat socket cap screws? They’re often present in vehicles, machines, tools and in some engineering applications. Flat socket cap screws are just small enough and just tough enough that they are ideal for delivering long-term and reliable performance in tight spaces like those you would find in machines, tools and vehicles.

Common Flat Socket Cap Screw Materials

Almost all flat socket cap screws are made of high-strength steel. You’ll find options that are made of stainless steel and black oxide alloy steel as well as other tough materials that are proven and tested in harsh environments — such as those under the hoods of vehicles or within the casings or machine tools.

You can also find flat socket cap screws with different heads and different threads. Choose carefully to make sure you’re getting exactly what you want and need in a flat socket cap screw.

Why Choose Flat Socket Cap Screws

Flat socket cap screws are best in areas where space is tight. That’s why they so often find use in tools and machinery, where space is at a premium and casings often cannot accommodate more substantial fasteners. Because they’re so small and because they’re used in such tight spaces, flat socket cap screws must be made from the toughest materials and tested to prove their strength in performance.

Flat socket cap screws — and other types of socket cap screws — are known for their safety, reliability and affordability.
