True German Quality standards

As an engineer, I am picky about fasteners. These meet the DIN 7991 specifications perfectly. The threading is clean, and the material feels durable. Will definitely reorder.

Perfect for precision electronics

These screws are exactly what I needed for my project. The thin head allows them to sit flush perfectly, and the stainless steel quality is top-notch. No stripping issues with my hex key.

Excellent small hardware

Hard to find high-quality small countersunk screws locally. These fit my needs perfectly for repairing my laptop casing. The one-turn secure fit claim is accurate; they lock in nicely.

Sizes run slightly tight

The quality is good, but I found the M3 threads to be a bit tight when going into standard nuts. Had to tap them out slightly. Otherwise, they work as described.

Good value, fast shipping

Solid screws for the price. I used the M4 size for a furniture repair. They hold well and look clean. One star off only because the box was slightly dented on arrival, but the contents were fine.

Great for outdoor use

I used these for a garden trellis assembly. Since they are 304 stainless, I don't have to worry about rust. They have been exposed to rain for a month now and still look brand new.

5 FAQ

Q: Is the head height truly ultra-thin compared to standard pan heads?

A: Yes, the 7991 standard specifies a lower profile than typical pan head screws, allowing for a more streamlined finish in tight clearance applications.

Q: Do you sell these in bulk packs of 500?

A: Currently, we stock them in boxes of 100. However, you can purchase 5 boxes for a bulk discount automatically applied at checkout.

Q: Can these be used in marine environments?

A: While 304 stainless steel offers good corrosion resistance, for direct saltwater immersion or harsh marine environments, we recommend our 316 grade stainless steel screws for maximum longevity.

Q: Are these screws compatible with aluminum frames?

A: Yes, 304 stainless steel is generally compatible with aluminum, though we recommend using an anti-seize compound to prevent galvanic corrosion in wet environments.

Q: What size hex key do I need for the M5 screws?

A: For the M5 Ultra-Thin 7991 screws, you will need a 4mm hex key (Allen wrench) for proper installation.
