3/8" x 12" 육각 머리 랙 나사 | 316 스테인리스 스틸 (75 / 팩)

Finally, a lag screw that doesn't strip out when driving into dense oak—these 316 stainless ones bit in cleanly and the threads held perfectly. The 12-inch length gave me the extra bite I needed for a heavy timber beam repair.

Put in 75 of these across a timber frame tie-down and they drove in clean without a single bent shaft. The 316 stainless heads held up through a week of coastal rain with zero surface rust, which is exactly what I needed for exterior work.

I was a little worried about stripped threads on a 12-inch fastener, but these cut into the timber cleanly and the 316 stainless finish is flawless. Perfect for the deck frame I’m building near salt water, and the 75-count box means I’ve got plenty of spares.
