High-Quality Hex Nuts

What is a Hex Nut?

Hex nuts feature an interior thread designed to be screwed onto a hex bolt with a matching thread. The use of a hex nut provides a strong, secure joint with the bolt that is highly capable of withstanding heavy wear, stress, and strain. As a result, hex nuts and bolts are the primary fastening choice in countless industrial applications that require a reliable hold under constant movement and heavy loads. Common uses include heavy machinery, engines, motors, industrial equipment, and commercial furniture.

Comprehensive Hex Nut Inventory

Since 1988, U-Bolt-It has been a leading distributor and manufacturer of high-quality hex nuts for all major industries. We stock an extensive inventory from the top manufacturers in the industry, including:

• Standard Hex Nuts: The six-sided hexagonal shape is the standard used in all industries to securely fasten items. Generally hand-tightened or tightened with a wrench, they can be used with bolts of all styles and sizes.
• Jam Nuts: Designed to press against another nut and acting as a locknut to prevent loosening, jam nuts are manufactured at only half the height of a standard hex nut.
• Kep Nuts (K-Lock Nuts): A pre-assembled nut and free-spinning washer that makes product assembly much more convenient. When tightened, the teeth of the lock washer dig securely into the item’s surface.
• L9 Hex Nuts: Featuring incredible tensile strength and special features that control torque-tension characteristics, L9 nuts allow for maximum holding power in high clamp loads. Ideal for automotive, aerospace, and construction applications.
• Slotted Hex Nuts: Designed to be used with a cotter pin that passes through a drilled hole in the mating bolt or stud, effectively preventing the nut from ever loosening.
• Tee Nuts (Blind Nuts): Ideal for structural assembly and the manufacture of products to easily fasten wood, plastic, or composite materials.
• Nylon Insert Locknuts (Nyloc): Used in applications involving heavy vibration or motion, these locknuts resist loosening and can be reused up to fifteen times. Note: Nyloc nuts should not be used in high-temp environments or harsh chemical exposures.
• Wing Nuts: Designed with two large metal wings, these are excellent for hand-turning applications where frequent disassembly and reassembly are required.
• Rod Couplings: Elongated nuts used to seamlessly join two externally threaded parts of equal thread diameter and pitch, including rods or pipes.

Manufacturing Materials and Custom Finishes

U-Bolt-It supplies a full line of hex nuts with a standard UNC thread, though expert custom cutting, chamfering, and threading options are readily available at our facility. Our strong, reliable, and high-performing hex nuts are available in standard steel alloys, carbon steel, and stainless steel, as well as rare and exotic materials for specialty applications.

To ensure your finished product meets your exact requirements and the tightest environmental tolerances, we also offer custom coating and finishing services, including Zinc, Teflon®, Xylan®, Cadmium, and hot-dipped galvanized plating.
