5-Pack Alloy Steel Shoulder Bolts – 1/4'' Shoulder Dia X 1'' Length, #10-24 UNC Thread, Black Oxide, Grade 12.9 Hex Socket

About This Product

These shoulder bolts are tough little fasteners made from high-grade alloy steel with a black oxide finish.

Each one has a 1/4-inch shoulder diameter and a 1-inch shoulder length, with #10-24 UNC coarse threads on the end.
The hex socket drive lets you crank them down with an Allen wrench or hex bit, and the Grade 12.
9 rating means they're seriously strong – way stronger than your average hardware store bolt.

The smooth shoulder section is designed for parts that need to rotate or pivot, like pulleys, linkages, or guide rollers.
Unlike fully threaded bolts, the unthreaded shoulder gives a precise bearing surface and reduces wear on moving parts.

Coarse threads also mean faster assembly and disassembly, which is nice when you're doing repairs or adjustments.

Commonly used in automotive, machinery, and industrial applications.
This 5-pack gives you enough for small projects or spares.

Solid construction, corrosion-resistant black oxide coating, and precision-made to ISO7979 specs.

Reliable and no-nonsense.
