HOLO-KROME 07048 1-14 內六角螺帽 | 12點套筒驅動 | 合金鋼熱處理黑色氧化 (25個/包)

The 12-point socket drive is a perfect fit for tight spaces where a standard wrench can’t reach, and the black oxide finish feels durable right out of the package. Used a few on a machinery repair, and they held up without any stripping.

The knurled texture makes these much easier to hold while starting the thread, and the 12-point drive takes standard hex keys without issue. I've used a dozen so far on a tight engine bracket and they grip perfectly.

These are the first batch of 1-4 Allenuts I've tried with a 12-point socket drive, and the black oxide finish really helps them grip without slipping on the shaft. Used them in a tight spot where a regular wrench wouldn't fit, and they held up perfectly during installation.
