M6-1 X 140mm 六角穴付きキャップスクリュー | 六角穴ドライブ | 半ねじ | 316ステンレス鋼 (50 / パック)

I needed longer bolts for a marine railing repair, and these 140mm screws in 316 stainless gave me the corrosion resistance I was after. The partial threading made aligning the assembly much easier than full-thread alternatives I've used before.

Packaged decently and every screw threads cleanly into the hex socket. The 140mm length was just right for bolting down a heavy jig base, and the partial threading made alignment much easier than with fully threaded bolts.

Used these for a marine railing repair I’ve been putting off—the 140mm length and partial thread made alignment easy, and the 316 stainless held up to the salt spray test.
