Good Value
Solid screws for the price. One of the 3/8 bolts had a slightly burred head, but the rest were perfect. Would buy again.

Perfect for Marine Use
I used these on a boat fixture. No signs of corrosion after three months of exposure. Very satisfied with the stainless quality.

Excellent Thread Quality
Used these for a custom jig build. The threads engaged smoothly without any cross-threading issues. The 304 steel holds up well in my workshop environment.

Great Assortment
Having multiple sizes in one kit saved me a trip to the hardware store. The hex sockets are deep enough for standard keys.

Precise Measurements
I caliper checked the diameters and pitches. They match the SAE specs exactly. Great for precision assembly work.
Q: Is a tax invoice included with the shipment?
A: Yes, as per our policy, a free special invoice is included with every order for your records.
Q: Are these screws suitable for outdoor use?
A: Yes, 304 Stainless Steel offers good corrosion resistance for most outdoor environments, though 316 is recommended for saltwater.
Q: What size Allen wrench do I need for the 1/4"-20 screws?
A: You will typically need a 3/16" hex key for the 1/4" button head screws. Please check the specific head size upon arrival.
Q: What is the tensile strength of these bolts?
A: These are standard 304 stainless fasteners, suitable for general mechanical applications. Specific load ratings depend on the size.
Q: Do these come with matching nuts?
