ASTM A307 Galvanized Hex Cap Screws
Hex cap screws are commonly found in industrial applications including pipe flanges, covered bridge construction and restoration, and certain marine construction projects. All ASTM-A307 galvanized hex cap screws sold by Brazos Fasteners meet ASTM-specifications.
Types of ASTM-A307 Bolts
The ASTM-A307-A specification applies to certain carbon steel bolts, studs, and threaded rods with a tensile strength of 60,000. The A307-B have a tensile strength of between 60,000-120,000 PSI, they also have a heavy hex head, and are typically used for flange joints, pipe systems, and cast iron flanges.
The diameters of A307 bolts range from 1/4 inch to 4 inches. There are three grades of ASTM-A307 hex cap screws: A, B, and C, although ASTM replaced C with specification F1554 Gr 36.
A and B, offer different mechanical and chemical properties for specific applications.
All ASTM-A307 hex cap screws have the following:
- A hexagonal head with a flat washer facing underneath
- Machine threads in partial or fully threaded, that can be used with a nut or in a tapped hole
- No seams on bearing surfaces
The typical finish for the ASTM-A307 bolts is galvanized, this coating on hex cap screws will help resist corrosion from demanding environmental factors common to our coastal location. We also stock plain finish, but they can also be plated in zinc or cadmium.
Uses for ASTM A307 Galvanized Hex Cap Screws
These screws have applications in numerous industries:
A307 screws are well-suited for use in the oil and gas industries on pipe flanges, as anchor bolts, and in general construction projects.
A307 hex head screws are ideal for pipe flanges in water treatment plants and as anchor bolts for solar arrays and transmission towers.
