Liberty Supply carries the fasteners that hold shops, fleets and jobsites together: hex bolts and cap screws in Grade 2, 5 and 8, socket head cap screws, machine screws, nuts, washers, anchors for concrete and masonry, rivets and threaded rod.

Every fastener page can be narrowed by diameter, thread size (for example 3/8"-16 or M8 x 1.25), thread type, length, material, finish, grade and package quantity, so you can go straight to the exact part.

How to choose the right fastener

• Match the thread. Coarse thread (UNC) is the general-purpose choice and is less likely to cross-thread. Fine thread (UNF) gives more thread engagement in thin walls and better adjustment. Metric sizes list diameter and pitch, such as M10 x 1.5. See how to read thread sizes.
• Pick the strength grade. Grade 2 is low-carbon steel for light duty, Grade 5 is medium-carbon heat-treated steel for automotive and equipment work, and Grade 8 is alloy steel for high-stress joints. Use nuts and washers of matching grade. Our guide to hex bolt grades shows the head markings.
• Choose a material and finish for the environment. Zinc plating suits dry indoor use, hot-dip galvanized resists outdoor weather, and 18-8 or 316 stainless handles moisture and washdown areas.
• Measure length correctly. Most bolts and screws are measured from under the head to the tip. Flat head screws are measured overall, because the head sits flush.
• Use the right fastener for the base material. Concrete and block call for anchors, wood and sheet metal call for self-tapping and wood screws, and blind joints in sheet metal often call for rivets.

If your team pulls the same sizes every week, a business account on terms keeps purchasing simple, and our vendor managed inventory program relabels your bins and adds QR codes for reordering. Our line cards show the full range of hardware we source.

Common questions

What is the difference between a hex bolt and a hex cap screw?

The two look almost the same. A hex cap screw is made to tighter tolerances and has a washer face under the head, so it can be turned into a tapped hole. A hex bolt is usually paired with a nut.

Can I mix stainless and zinc-plated steel fasteners?

It is better not to. Dissimilar metals in contact can lead to galvanic corrosion, especially outdoors or in wet areas, so match the bolt, nut and washer material.

How do I tell a Grade 5 bolt from a Grade 8?

Look at the head. Grade 5 hex bolts have three radial lines, Grade 8 bolts have six, and Grade 2 bolts have no lines.
