1-1/4-7 X 5-1/2" براغي رأس سداسي ثقيلة | ستانلس ستيل 316 | خيط جزئي (2/عبوة)

Picked up a pack for a trailer hitch repair on my boat trailer. The 316 stainless held up perfectly in the salt spray without any corrosion after a month. Good to have a sturdy, partially threaded option for a tight fit.

Installed these on a saltwater tank mount and the 316 stainless is holding up perfectly against the constant moisture. The threads cut clean and the partial threading made alignment easier than fully threaded bolts.

Finally got these in for a rebuild job, and the 316 stainless is exactly what I needed for the salt-air environment. The partial threading made alignment a breeze, and the hex heads grabbed a wrench without any slipping.
