3/8 英吋 x 7 英吋 內六角肩螺絲 | 內六角頭 | 內六角驅動 | 合金鋼 (25 個/包)

I needed a long shoulder screw for a bearing pivot, and the 7-inch length on these alloy steel ones was perfect. The precision-ground shoulder slid into a flange bearing with zero slop, exactly what I was hoping for. They’re solid through and through, no complaints.

These things are beefy. The hex socket drive seated the wrench cleanly and the 7-inch length gave me plenty of reach as an axle on my jig, and the shoulder stayed true when I torqued it down.

These bolts are exactly what I needed for a custom furniture pivot point—the precision-ground shoulder slides through a bushing without any binding. And the hex socket drive makes installation a breeze with no stripped heads. Much better than standard hardware for this job.
