A 199-piece mixed tray of zinc plated, clear passivated hex head set screws with matching nuts and washers. A solid general-purpose selection to keep in the van or on the bench for everyday fixing jobs.
This mixed tray gives you 199 pieces of zinc plated, clear passivated set screws with conforming nuts and washers, all in one go. If you have ever spent ten minutes rummaging through a toolbox for the right M6 nut, you will understand why a well-organised selection tray like this earns its keep. The set screws nuts and washers are sorted by size, so finding what you need takes seconds rather than a small eternity.
The zinc plating and clear passivation give a decent level of corrosion resistance for general indoor and light outdoor use. These are not marine-grade fixings, but for most day-to-day applications on site or in a workshop, they hold up well. The hex head design means you can drive them with a spanner or socket, which makes them faster and more reliable to tighten than a slotted screw in most situations.
Where Set Screws, Nuts and Washers Get Used
This kind of mixed selection is useful across a wide range of trades. Electricians, plumbers, joiners, and general maintenance teams all reach for this type of fixing regularly. The tray format keeps sizes separated, which matters when you are working at pace and cannot afford to mix up an M5 with an M6.
What the Tray Contains
The selection includes a range of metric sizes, each with conforming nuts and flat washers. Having the washer in the set is a detail worth noting. A washer distributes the clamping load and protects the surface, which is something that gets skipped when you are working off a bag of loose fixings and the right size washer is nowhere to be found.
At this price, it makes sense to keep a couple of trays on the van. Fewer trips to the merchant for a single bolt is always a win.
Pro Tip: Check the tray after the first few jobs and top up any sizes you go through quickly before the compartments run dry, otherwise you end up with 180 M3 screws and nothing useful left.
This mixed tray is suited to general maintenance, light fabrication, electrical installation, plumbing, joinery, and workshop repairs. The selection of metric set screws with nuts and washers covers the most common fixing sizes you will encounter on a typical job. It is a practical addition to any service van, site toolbox, or workshop bench where you need a reliable supply of standard metric fastenings without placing individual orders for each size.

Select the correct set screw size from the tray for your application
Place a flat washer onto the screw shank before insertion if surface protection is needed
Insert the screw through the fixing point and thread the conforming nut on by hand
Tighten with a spanner or socket, adding a washer under the nut where required
Check the fixing is secure and no threads have been cross-threaded before completing the job
What sizes are included in the 199-piece mixed tray?
The tray contains a selection of common metric sizes. The exact breakdown is shown on the tray label, but the set is designed to cover the most frequently used sizes for general maintenance and installation work, with each size having conforming nuts and washers included.
Are these fixings suitable for outdoor use?
The zinc plating and clear passivation provide reasonable corrosion resistance for light outdoor or intermittently exposed conditions. For applications that will be permanently exposed to the weather or moisture, stainless steel fixings would be a more appropriate choice.
The set screws in this tray are manufactured to standard metric dimensions with a zinc electroplated finish followed by clear passivation, which improves resistance to white rust formation. The hex head design conforms to standard DIN or equivalent specification, allowing use with standard metric spanners and sockets. Conforming nuts and flat washers are included for each size in the selection.
