FAQs
What’s the difference between socket head cap and hex head cap screws?
Socket head cap uses an internal hex (Allen) drive and a compact cylindrical head; hex head cap uses an external hex for wrench/socket access.
Which socket style offers the highest preload?
Socket head cap typically delivers the highest preload thanks to deeper drive engagement and robust head geometry.
Can I use socket screws outdoors?
Yes—choose 18-8 stainless for corrosion resistance. For maximum indoor strength, alloy steel black oxide is common.
