Fit for the purpose
plastic case came cracked, but that is pretty much par for the course Product description says that they are alloy steel. Bolts are stamped 10.9. Metric 10.9: Similar to SAE Grade 8 (depends on context) FYI: Common Metric Grades: 4.6: General use (low/medium carbon). 8.8: Automotive, machinery (medium carbon). 10.9, High strength, alloy steel. 12.9: High strength, high-carbon alloy steel, quenched (or titanium)

Excellent for applications where the bolt will be visible such as show vehicles
Quality made with good black coat finish. Good for use when bolts will be visible. Reasonably priced for what you get. Would buy again

Good flange bolts
Very decent bolts. The M8-1.25X50 and not easy to find in a flange head and I was happy find these bolts. The coating they use does not seem to be a quality full on black protective coating. I noticed that their coating comes off very easily. Just running the bolt into a nut and back out on a piece of equipment shows it has scraped off. Unfortunately I have to use these bolts in repeated installation and removal application and I doubt this coating will last. Having them rated at grade 10.9 is a very good strength for about every application.

Good products and new packaging.
Great replacement engine machine bolts. Arrived fast and the packaging is great in a small plastic box instead of the old zip lock bags that arrive with holes from shipping. Great seller, great products.

Perfect Fit for My 2025 Chevy 2500 Running Boards
These replacement bolts are perfect for my 2025 Chevrolet 2500 running boards. They fit the factory-installed threaded connection points on the frame exactly, making installation quick and hassle-free. Very happy with the quality!
