Studbolts

Studbolts are fully threaded rods with threads on both ends, used in conjunction with two nuts to secure flanged connections in pipelines, pressure vessels, and other high-stress industrial environments. 

LoneStar Fasteners offers a wide range of high-quality stud bolts designed for industries such as oil, gas, and petrochemical sectors. Their stud bolts come in various ASTM grades like A193 B7, B7M, and B16, which are well-known for their high strength and reliability, particularly in high-temperature and high-pressure environments.

These stud bolts are available in full-threaded varieties and can be customized with different coatings such as zinc, PTFE (Teflon), and hot-dip galvanizing for enhanced corrosion resistance. This makes them ideal for use in harsh conditions like offshore drilling platforms and refineries. LoneStar also manufactures double-ended studs, waisted studs, and fully-threaded sets to meet diverse engineering requirements.

With over 30 years of experience, LoneStar is recognized for providing products with short lead times and extensive certifications, making them a trusted partner for critical industrial applications.
