مسامير نقل 1/4-20 × 5/8" | ملولبة بالكامل | فولاذ عادي درجة A307 (400 / عبوة)

The square neck underneath grabbed the wood instantly when I tightened them, so no spinning or cursing during assembly. Having 400 in one box means I’ve got plenty left over for future projects, and the plain steel finish is exactly what I expected for the price.

Put these on my trailer deck rebuild and the square neck locked in perfectly as I tightened them down. The full threading on the 5/8" length made it easy to get a solid bite with the nut.

The square neck under the head grabbed perfectly in the wood, so I didn't need a second wrench to tighten them. These plain steel bolts have a solid feel and the 5/8" length was spot-on for my project. A full box of 400 means I have plenty left over for future builds.
