Product Description

Stainless Allen head bolts feature a smooth cylindrical head and an interior hex socket for use with an Allen key in order to apply torque to the bolt without harming the Allen key or the bolt. These secure fastening Allen bolts are recommended where space is at a premium, allowing recessed or countersunk installation and providing superior clamping force. These fasteners come in various materials, including high-tensile alloy steel for demanding applications and stainless steel for applications where corrosion resistance is a concern, and are highly appreciated for their strength, accuracy, and good looks.
