Why choose 410 stainless steel

410 stainless combines hardness and wear resistance with reliable corrosion resistance for many indoor and semi-outdoor applications. It’s a cost-effective choice for general purpose fasteners. Note that while 410 offers good corrosion resistance, it is not as corrosion-resistant as 304 or 316 stainless steel, so avoid highly salty or aggressive environments if possible.

Sizing and compatibility

Ensure you have a compatible nut or tapped hole for 1/4-20 threads. The 1/2″ length provides enough engagement for typical metal-to-metal joints while keeping a compact profile. If you need a longer or shorter screw, consider adjusting length to achieve proper thread engagement.
