AMLOOPH M3.5 wood screws assortment (190pc) in plastic box

What this is for

If you’re doing wood work, small repairs, or general carpentry around the home, the one problem you’ll keep running into is simple: you never seem to have the right screw length when you need it. The AMLOOPH M3.5 Wood Screws Assortment is built for that “grab the correct length and carry on” moment.

This is a mixed set of M3.5 self-tapping wood screws supplied in a plastic storage box with separate compartments for each size. The idea is that you can keep one kit on hand and avoid rummaging through drawers or making an extra trip for a single, specific screw.

Key points

You get 6 different screw lengths within the same thread size (M3.5), so you’re not locked into one fastening depth.

On paper, it’s aimed at straightforward timber and sheet material fastening where coarse-thread screws help them bite securely. The included set is also designed to be easier to manage than loose screws, thanks to the compartmentalised plastic box.

That said, “assortment” kits are never perfect for every job. If your work repeatedly needs one specific length, you may find it costs more per screw than buying a single size in bulk.

The essentials: sizes, materials and storage

The pack totals 190 screws, split across the lengths below (all with a 3.5mm thread diameter):

• 40pcs M3.5 x 16mm
• 35pcs M3.5 x 20mm
• 30pcs M3.5 x 25mm
• 25pcs M3.5 x 30mm
• 30pcs M3.5 x 35mm
• 30pcs M3.5 x 40mm

The screws are described as being made of carbon steel with high-temperature zinc plated and yellow passivated coating. In practical terms, that combination is intended to help reduce rusting and bending, which matters when you’re driving screws into timber and don’t want weak points.

There’s also mention of a “screws and wall plugs set” in the description. However, the exact plug details aren’t specified in the information provided, so it’s worth checking what’s actually inside your specific box listing before you plan a masonry-involving job.

For storage, the kit comes in a plastic box with separate compartments by screw size. For anyone who’s ever poured loose screws out onto a bench and regretted it, this is a genuinely useful approach.

What stands out in day-to-day use

1) A range of lengths without switching packs

Because it includes 16mm through to 40mm, it covers a lot of typical quick fixes—think attaching brackets, securing timber offcuts, or fixing down wood boards where the thickness varies.

2) Coarse thread and self-tapping design

The screws are described as coarse-threaded with sharp tips and a smooth surface, intended to bite into materials like softwood, hardwood, particleboard, and fibreboard.

If you’re doing a small decking-style or timber fastening job, the coarse-thread approach is often chosen for grip rather than fine, delicate threads.

3) Useful for a “mixed toolbox” approach

The description lists broad potential applications such as furniture screws, fence screws, door handle screws, shed security uses, and also masonry/concrete-related wording. That variety suggests the kit is meant to be a versatile general-purpose selection rather than a specialist screw for one single job.

Still, if you’re working with one material repeatedly (for example, thick structural timber), you may need to compare whether a dedicated screw type for that material would perform better.

Where it shines (and where it can fall short)

This assortment makes the most sense when:

• you want one kit that covers multiple thicknesses
• you’re regularly doing DIY tasks where the screw length may change from job to job
• you value neat storage and quick selection

It may not be the best match if:

• you only ever use one screw length and want the lowest cost per screw
• you need high precision for a specific application (in those cases, a dedicated screw size and type can be more predictable)
• you’re depending on the set for masonry/concrete work without verifying whether appropriate wall plugs are included and suitable

Also, while the coating is described as zinc plated with yellow passivation (intended to resist rusting and bending), no screw set is truly maintenance-free. For outdoor use, you’ll still want to choose good mounting practices and avoid leaving things exposed longer than necessary.

Getting the most from it: practical tips

A small workflow improvement can make a big difference with self-tapping screws.

Before driving a screw, it’s worth matching the length to what you’re attaching—so the screw goes in with enough bite, without poking through where it shouldn’t. With this kit, that choice is easier because you can select from 16mm up to 40mm rather than forcing a compromise.

Micro-example: if you’re re-attaching a timber board to a thicker batten, you can start by deciding how much of the board thickness you need to pass through, then pick the shortest screw that still gives adequate engagement. If it feels like you’re using too short a screw, you’ve got the next length up in the same box—no need to stop the job and search.

If you’re fastening into particleboard or fibreboard, don’t assume every screw will behave the same: pilot guidance and careful driving often help prevent damage to the panel edges.

FAQs

What sizes are included in the 190pc set?

It includes M3.5 screws in six lengths: 16mm, 20mm, 25mm, 30mm, 35mm and 40mm.

Is this suitable for outdoor use?

The screws are described as zinc plated and yellow passivated, which is intended to help reduce rusting. That suggests outdoor-capable use for many DIY scenarios, but it’s still wise to consider your local weather exposure and fixing method.

Is this only for wood?

It’s clearly presented as a wood screw set, with the description calling out softwood, hardwood, particleboard and fibreboard. It also mentions wall plugs and a broader range of applications, but the exact plug suitability isn’t detailed here.

Does the kit include a storage box?

Yes. It’s supplied in a plastic storage box with separate compartments for each screw size.

Final verdict

When it makes sense

It’s a solid pick if you do frequent small wood projects and want a ready mix of M3.5 screw lengths in one compartmented plastic box. The assortment saves time, and the self-tapping, coarse-thread approach is designed for secure fastening into common timber and board materials.

Should you buy it?

Worth considering if you want flexibility more than you want one “perfect” screw for a single job. You may want to skip it if you only ever need one length, or if you’re planning masonry/concrete fixes and you’d rather confirm plug compatibility before committing.
