Bolts, nuts and washers are the fasteners that stop fittings creeping, brackets loosening and assemblies rattling over time. When the sizing is off or the stack-up isn’t right, you get the usual headaches: parts twisting as you tighten, threads stripping, or a fixing that won’t pull up square. At Orion Supplies, you can buy bolts, nuts & washers online for everyday maintenance work, small installs and replacement jobs where you need a secure clamp and a tidy finish.
This range covers the core hardware used to clamp parts together, spread load, and keep joints stable. It suits jobs where a threaded fastening is the right answer, especially where you need a controlled pull-up and the option to remove and refit later.
Priorities:
Bolts are used where you want a positive mechanical clamp rather than a screw biting into a base material. They’re practical for brackets, fittings and assemblies that need a firm pull-up and predictable alignment.
Common uses include:
A bolt that’s too short won’t clamp properly. Too long and you end up fighting protruding thread or fouling behind the fitting.
The nut matters as much as the bolt. A good match tightens smoothly, holds under vibration, and doesn’t chew the thread when you’re working quickly.
Typical choices are driven by:
If you’re topping up for site work, keeping a small set of common sizes avoids the “nearly fits” problem that wastes time.
Washers do three useful jobs: they spread load so the surface doesn’t dish, they help spacing where you need a cleaner stack, and they support sealing in wet connections where a washer is part of the joint.
Where they help most:
If the fixing is marking the surface or the joint keeps settling after tightening, washer choice is often the fix.
For some maintenance jobs, a kit saves time because everything you need is in one pack. That’s useful on common replacements where missing one washer or nut turns into a second run.
These packs are handy for:
A quick check here prevents mismatched threads and weak pull-up:
Thread and size
Match diameter and thread type across bolt and nut. If it doesn’t spin freely by hand at the start, stop and re-check.
Length and engagement
You want solid engagement through the nut without excess thread causing clearance issues behind the fitting.
Washer requirement
Use washers where you need load spread, surface protection, spacing, or a sealing component in a wet joint.
Material and finish
Choose a finish that suits the environment, especially where damp causes early corrosion marks.
Access and tools
Make sure you can actually tighten the hardware in the space available with the tools on hand.
Buy bolts, nuts & washers online at Orion Supplies for secure clamping, cleaner pull-up and fewer loose fittings after handover. If you’re building out the order, add roof fasteners, wood screws, specialist screws, or nails, threaded rods to keep the everyday fixings together.
A bolt is typically used with a nut or a pre-threaded fitting to clamp parts together. A screw usually forms its hold by biting into the base material.
Match the nut to the bolt’s diameter and thread. If you’re replacing an existing fixing, match like-for-like to avoid cross-threading and poor clamp.
Use a washer when you need to spread load, protect the surface under the head or nut, take up small spacing, or support a sealed joint where a washer is part of the connection.
Most issues come from thread mismatch, damaged threads, debris in the thread, or starting the nut at an angle. Start by hand and make sure it runs freely before tightening.
You want enough engagement for a secure clamp without bottoming out or leaving the nut only half on. If the joint feels tight before it’s clamped, the length or stack-up is wrong.
