Essential for machinery repair
I use these for repairing conveyor belt guides. The combination of the spring washer prevents loosening due to vibration effectively. Highly recommend for any mechanical application.

Good variety pack
The kit covers all the common sizes I need. The M6 and M8 sizes are my most used. Only wish the case had better labeling for each compartment, but the screws themselves are top-notch.

Great quality, slightly tight fit
The stainless steel quality is excellent and they look great. The washers are held on tightly, which is good for shipping but required a bit of extra torque to start threading. Overall very satisfied.

Convenient and rust-resistant
Bought these for an outdoor garden bench project. After several months of exposure to rain, there is no sign of rust. The integrated design makes installation much faster.

Professional grade fasteners
As an electronics assembler, precision matters. These screws have clean threads and the hex heads don't strip easily. The three-piece combo ensures a secure connection every time.

Perfect all-in-one solution
These integrated screws save so much time during assembly. Having the flat and spring washers pre-attached is a game changer for my workshop projects. The 304 steel feels very durable.
Q: What is the hardness rating of these bolts?
A: These are standard 304 Stainless Steel fasteners, typically corresponding to a strength class of A2-70, which is suitable for most general industrial and commercial applications.
Q: Can the washers be removed if I only need the screw?
A: The washers are designed to stay attached during installation for convenience. While they can be forced off, it may damage the finish. We recommend using them as an integrated unit.
Q: Are these suitable for marine environments?
A: While 304 Stainless Steel offers good corrosion resistance, for constant exposure to saltwater or harsh marine environments, we recommend 316 Stainless Steel for superior protection.
Q: Do these screws come with the Allen key needed to install them?
A: No, this kit includes only the integrated screws. You will need to use your own metric hex key set appropriate for the specific screw size you are using.
Q: Is there a bulk discount available for ordering multiple kits?
A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly or add large quantities to your cart to see the automatic discount applied at checkout.
