1/2 inch x 1 1/2 inch UNC 13 Tpi Socket Cap Black High Tensile bolts pack of 4. for CNC Machinist T Slot Fixture Bolts

1/2 inch x 1-1/2 inch UNC Socket Cap Bolts - Black High Tensile Grade 8 - Pack of 4

Black self-colour 1/2 inch UNC socket cap bolts with a 1-1/2 inch length, manufactured from high tensile Grade 8 steel. The extra 1/4 inch over the 1-1/4 inch variant makes these the preferred choice where deeper thread engagement is needed — such as thicker T-slot fixture plates, heavier machine beds, or assemblies where the bolt must pass through a spacer or additional material layer before engaging the nut. The tall cylindrical head provides a solid bearing surface and accepts a standard hex/Allen key for maximum torque application.
