Button Head Bolt Views
A socket cap screw, also known as a socket head cap screw, socket screw or Allen bolt, this is a type of cap screw with a hexagonal recessed drive. The most common types in use have a cylindrical head whose diameter is nominally 1.5 times (1960 series design) that of the screw shank (major) diameter. Counterbored holes in parts allow the screw head to be flush with the surface or recessed. Other head designs include button head and flat head, the latter designed to be seated into countersunk holes. A hex key (sometimes referred to as an Allen wrench or Allen key) or hex driver is required to tighten or loosen a socket screw. Socket screws are commonly used in assemblies that do not provide sufficient clearance for a conventional wrench or socket.
These are 12v LED lighted bolts made from high grade stainless steel and polished to a mirror finish. The light shines brightly through the hex head opening. They can be used for many applications: gauge lights, indicator lights, accent lights, etc. They are 5/16
Button head bolts (round head) are commonly used in wood connections. Button head bolts are similar to carriage bolts, but without the square neck under the head. Because they are used with wood, button head bolts are rarely high strength and virtually always supplied in a standard ASTM A307 specification.
Portland Bolt manufactures button head bolts from 1/2o" through 1-1/4 e" diameter in most ASTM, AASHTO, and SAE specifications. Special tooling can be created to produce nonstandard head dimensions, button head bolts larger than 1-1/4l" in diameter, or bolt heads with your companies name and/or logo.
