براغي ذات رأس مقبس 1/2-13 × 5 بوصة | محرك سداسي المقبس | صناعة أمريكية | فولاذ سبائكي مع أكسيد أسود حراري (200 / عبوة)

Got these for a jig I was building, and the 5-inch length was perfect for clamping down thicker stock. The hex drive seated smoothly without any cam-out, and the black oxide finish feels durable.

Used a handful of these for building a welding jig, and the black oxide finish held up perfectly against minor sparks and grime. The hex socket drive made it quick to get them torqued down without stripping. Exactly what I needed for heavy-duty fixturing.

These threads drive in perfectly with a hex key and the black oxide finish looks sharp on my jig frames. For a full box of 200, the alloy steel is rigid and the 5" length is exactly what I needed for clamping heavy fixtures.
