What are the types of metal fasteners?
Using the wrong fastener leads to weak joints, part failure, and costly repairs. Metal fasteners include bolts, screws, rivets, anchors, nuts, washers, and clips. Each fastener type handles different loads, materials, and assembly methods. At Prime, we manufacture and supply a complete range of metal fasteners, tested for strength, corrosion resistance, and fit—customized for industries […]
What are the U-shaped fasteners called?
You’ve seen those U-shaped metal pieces—but what are they actually called? U-shaped fasteners are commonly known as U-bolts or staple nails. U-bolts secure pipes or rods to surfaces, while U-shaped nails, or fence staples, hold wire or mesh. Each has a specific industrial use. These fasteners are essential in construction, electrical, and mechanical applications. Learn […]
What is the rule of thumb for bolt size?
Choosing the wrong bolt size causes structural failure, stripped threads, or production delays. The rule of thumb for bolt size is to make the bolt diameter one-fourth of the material thickness in structural applications. Bolt length must also match grip length plus thread allowance. This guide explains how to select the right bolt size, what […]
How to measure nut bolt size?
Every B2B buyer knows that measuring nut and bolt size incorrectly results in assembly failures, cost overruns, and shipping headaches. I have helped hundreds of clients around the world solve these problems. Inaccurate sizing can destroy your project’s schedule and cause expensive returns. The good news: there are proven, easy steps to get it right. […]
How do you read bolt sizes?
Misreading bolt sizes leads to misfits, stripped threads, and unsafe assemblies. Bolt sizes are read by identifying diameter, thread pitch, and length. Codes like M10×1.5×30 describe the bolt’s metric size: 10 mm diameter, 1.5 mm pitch, and 30 mm length. Understanding bolt markings avoids costly mistakes. Many clients confuse thread pitch with length or mix […]
What is the black coating on steel bolts?

It provides mild corrosion resistance and a sleek look. But performance depends on application. Learn which coatings work best and how they compare. Many clients assume black coatings […]
What is the best anti seize for steel bolts?
Stuck bolts delay production and increase costs. The right anti-seize compound prevents these failures. Anti-seize compounds reduce friction and prevent bolt galling and rust. The right type depends on temperature, materials, and corrosion risk. Copper and nickel-based formulas dominate the market. Learn which works best for your needs. Choosing the wrong anti-seize leads to seized […]
