Perfect assortment for my workshop

This kit has exactly the sizes I needed for various repair jobs. The 304 stainless steel feels durable and the hex sockets are precise, so no stripping occurred during installation.

Good quality, great organization

The plastic box keeps everything neatly separated. The screws are high quality, though I wish there were slightly more M3 sizes included as I use those most often.

Rust resistant and strong

I used these for an outdoor garden project. After several months of exposure to rain, there is absolutely no sign of rust. The material quality is top-notch.

Fast shipping and great product

Arrived quickly and well-packaged. The variety of lengths within each diameter is very useful. Will definitely purchase from this seller again for future needs.

Solid hardware kit

Threads are clean and cut well. The hex drive fits standard Allen keys perfectly. Only minor issue was one compartment lid was slightly loose, but the screws didn't fall out.

Excellent value for money

Compared to buying individual packs, this assortment saves a lot of money. The flat heads sit flush perfectly in countersunk holes. Highly recommended for DIY enthusiasts.

5 FAQ

Q: Does this kit include different lengths for each diameter size?

A: Yes, the assortment includes multiple common lengths for each diameter (M2 through M8) to cover a wide range of application thicknesses.

Q: Are these screws suitable for marine environments?

A: While 304 Stainless Steel offers good corrosion resistance, we recommend 316 Stainless Steel for direct, constant exposure to saltwater marine environments.

Q: Is the storage box stackable?

A: The current design features a secure snap-close lid but does not have interlocking stacking features. It is designed to fit comfortably in standard tool drawers.

Q: Can I get a VAT invoice for this purchase?

A: Yes, as mentioned in the product description, a VAT invoice is available. Please ensure your company details are entered correctly at checkout or contact our support team after purchase.

Q: What size Allen key do I need for the M6 screws?

A: For standard metric M6 hex socket screws, you will typically need a 5mm Allen key or hex bit.
