What Our Hex Nuts Do For Your Build
Our hex nuts pair seamlessly with matching bolts and threaded studs to secure components in machinery, frames, panels, and fixtures. Manufactured to recognized international standards and offered in a variety of materials and finishes, they provide the grip you rely on, whether you’re tightening by hand on the line or driving fasteners at scale.
If your application calls for alternative profiles or functions, complement your setup with our Castle Nut for pinned, vibration-resistant joints, Wing Nut when fast tool-free adjustments matter, or Coupling Nut to join studs and extend threaded rod runs with precision.
Our ISO 4032 hex nuts follow the globally recognized metric profile for strength, geometry, and thread compatibility. This standard specifies across-the-flats dimensions, heights, and mechanical properties so your torque settings translate into predictable preload every time. Choose ISO 4032 when you need general-purpose reliability, broad material coverage, and easy interchangeability with other ISO-compliant fasteners already in your workflow.
Our DIN 934 hex nuts are the dependable six-sided workhorses used everywhere from fabrication shops to maintenance carts. They’re available in common property classes and stainless grades, with finishes that include plain, zinc, and other protective coatings to match your environment. When you want a familiar metric profile with deep size availability and smooth installation, DIN 934 is the standard that keeps projects moving.
Our BN 131 hex nuts adhere to a widely used metric profile that prioritizes consistent fit and dependable thread engagement. They integrate cleanly with standard bolts and studs, helping you maintain uniformity across mixed assemblies. If you need a straightforward, standards-aligned nut for daily production, BN 131 gives you the balance of quality and practicality you expect.
FAQs
What’s the difference between a hex nut and a lock nut?
A hex nut provides standard clamping force and is typically used with a flat or spring washer for general fastening. A lock nut adds a feature, such as a nylon insert, prevailing torque, or deformed threads, to resist loosening under vibration. If your assembly sees movement or shock, a lock nut or a hex nut paired with a locking method is the safer choice.
How do I loosen a hex nut?
Use a properly sized wrench or socket that fits snugly across the flats to avoid rounding. Apply steady counter-clockwise torque; if the nut is seized, a penetrating oil and a short wait can help break corrosion. For stubborn hardware, controlled heat or a longer handle for additional leverage may be necessary, just protect nearby components.
What do hex nuts look like?
Hex nuts have six flat sides for tool engagement and a central threaded hole that matches the bolt or stud. The outside flats are sized to standard across-the-flats dimensions, and the height is set by the governing standard. The result is a compact, easy-to-wrench profile that delivers strong, even clamping.
Is a hex nut a lug nut?
They share the hex shape, but a lug nut is specifically designed to secure wheels to vehicle hubs and often includes tapered or spherical seats. A standard hex nut is a general-purpose fastener used across countless mechanical and structural applications. If you’re working on wheels, use the correct lug nut style specified by the vehicle manufacturer.
