Perfect for my workshop projects

These studs are exactly what I needed for assembling a custom workbench. The threads are clean and cut precisely. Great value for the price.

Excellent rust resistance so far

I used these in a semi-humid garage environment for three months now, and there is no sign of rust. The 201 steel holds up well for indoor applications.

Smooth threads, easy installation

The nuts slide on very smoothly without cross-threading issues. Took off one star because the delivery took longer than expected, but the product itself is solid.

Great assortment kit

Having multiple sizes in one order saved me a trip to the hardware store. The packaging was secure, and nothing was missing.

Good quality, slight variation in length

Overall very satisfied. Most pieces were perfect, but I noticed one or two in the M6 pack were slightly shorter than advertised. Still usable for my needs.

Decent but not for heavy load

They work fine for light furniture assembly, but I wouldn't trust them for high-tension structural loads. Stick to 304 or 316 for critical outdoor projects.

5 FAQ

Q: What is the exact extended length of the M8 studs?

A: The extended length varies by specific sub-model selected at checkout. Please refer to the size chart in the product images or contact us with your specific order ID for exact measurements.

Q: Are these suitable for outdoor marine environments?

A: While they are rust-proof for general use, 201 stainless steel is not recommended for saltwater or harsh marine environments. We suggest 316 stainless steel for those conditions.

Q: Can I weld these studs directly to carbon steel?

A: Yes, they can be welded, but please note that welding may compromise the corrosion resistance near the weld zone. Proper post-weld treatment is recommended.

Q: Do these come with matching nuts?

A: This listing is for the double-end stud screws only. Nuts and washers are sold separately unless specified in a bundle option.

Q: Is the thread pitch standard coarse or fine?

A: All studs in this series feature standard coarse thread pitch (ISO metric standard) unless otherwise noted in the specific product title.
