HOLO-KROME 72094 1/4-20 X 5/8" 圓柱頭螺絲 | 六角驅動 | 合金鋼熱黑氧化物（每包100個）

I needed a solid batch of cap screws for a jig build, and these 1/4-20 x 5/8" ones cut down assembly time since the hex drive grabbed perfectly with a standard Allen key. The black oxide finish feels durable and hasn't shown any wear after a few cycles.

The black oxide coating on these screws holds up perfectly in my tooling fixtures without any rust or wear. They thread cleanly and the hex socket drive makes installation quick and precise. Exactly what I needed for precision assemblies.

The black oxide finish on these really holds up—no rust after a month in my humid shop, and the hex drive grips cleanly on the 100 pieces. They seated perfectly into my jig and haven't stripped a single thread.
