About Threaded Studs and Rods

Steel Heavy Hex Head Screws
for High-Pressure Applications

These Grade B7 steel screws are nearly twice as strong as our stainless steel screws for high-pressure applications. Also known as pressure bolts, they meet the high-pressure, high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

18-8 Stainless Steel Heavy Hex Head
Screws for High-Pressure Applications

These Grade B8 screws are made from 18-8 stainless steel and have good chemical resistance. Also known as pressure bolts, they meet the high-pressure and high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

Super-Corrosion-Resistant 316 Stainless Steel Heavy
Hex Head Screws for High-Pressure Applications

Made from 316 stainless steel, these Grade B8M screws are more corrosion resistant than 18-8 stainless steel screws and have excellent resistance to chemicals and salt water. Screws meet ASTM A193 regulations, so they can be used in high-pressure and high-temperature applications. Also known as pressure bolts.

High-Temperature Alloy Steel
Socket Head Screws—Grade B7

These screws are specially tempered to meet ASTM A193 specifications for temperatures up to 1100° F.

Medium-Strength Steel Threaded Rods

Medium-Strength Steel Threaded Rods—Grade B7

These Grade B7 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

Metric Fine-Thread Medium-Strength
Steel Threaded Rods—Grade B7

These metric Grade B7 fine-threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

Metric Medium-Strength Steel
Threaded Rods—Grade B7

These metric Grade B7 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

Left-Hand Threaded Medium-Strength
Steel Threaded Rods—Grade B7

Tighten these threaded rods by turning them to the left; once fastened, they resist loosening from counterclockwise motion.

Medium-Strength Steel Threaded Rods—Grade B16

Grade B16 threaded rods maintain their strength at higher temperatures than Grade B7 threaded rods. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

Stainless Steel Threaded Rods

18-8 Stainless Steel Threaded Rods—Grade B8

Grade B8 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges. They have good chemical resistance.

High-Strength 410 Stainless
Steel Threaded Rods—Grade B6

Stronger and more wear resistant than 18-8 stainless steel, these threaded rods are mildly chemical resistant. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

Metric Super-Corrosion-Resistant
316 Stainless Steel Threaded Rods

These metric 316 stainless steel threaded rods are more corrosion resistant than 18-8 and 410 stainless steel threaded rods and have excellent resistance to chemicals and salt water.

Super-Corrosion-Resistant 316 Stainless
Steel Threaded Rods—Grade B8M

Grade B8M threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

Hardened Super-Corrosion-Resistant 316
Stainless Steel Threaded Rods—Grade B8M

These hardened 316 stainless steel threaded rods are 40% stronger than standard Grade B8M threaded rods. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

Threaded Rod Assortments

Power Transmission

Acme Lead Screws and Nuts

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects.

Metric Lead Screws and Nuts

These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.

Corrosion-Resistant Fully Threaded Rod End Bolts

These rod end bolts are good for wet and corrosive environments—for maximum mounting flexibility, cut the fully threaded shaft to whatever length you need.

High-Strength Fully Threaded Rod End Bolts

These alloy steel rod end bolts have the highest tensile strength of any fully threaded rod end bolt we offer.

Eyebolts—For Lifting

Also known as machinery eyebolts.
