The 5/8-11 B7 stud 4 inch is a fully threaded fastener engineered for demanding industrial environments where strength, reliability, and consistency are non-negotiable. Manufactured to ASTM A193 Grade B7 from quenched-and-tempered chromium-molybdenum alloy steel, this stud delivers the dependable clamping force needed for high-pressure and elevated-temperature service. Whether you’re assembling critical equipment or maintaining existing systems, this stud provides the secure, long-lasting connection your application depends on.
Specifications
- Diameter: 5/8″
- Length: 4″
- Thread: 5/8″-11 UNC
- Material: Alloy steel (chromium-molybdenum)
- Specification: ASTM A193, Grade B7
- Finish: Plain
- Condition: New
Key Features
Specified to ASTM A193 B7: This stud meets the full mechanical requirements for Grade B7 in this diameter range, including a minimum tensile strength of 125,000 psi and a minimum yield strength of 105,000 psi. These properties make it well suited to bolted joints that must hold up under sustained load, internal pressure, and thermal cycling without loosening or failing.
Alloy steel construction: The chromium-molybdenum alloy used in B7 studs is heat-treated through a quench-and-temper process that develops both high strength and good toughness. This combination resists deformation and fatigue, giving you a fastener that performs reliably over the long haul rather than one that degrades under repeated stress.
Fully threaded design: With 5/8″-11 UNC threads running the full length, this stud offers flexible nut placement and accommodates joints of varying thickness. The coarse UNC thread pitch also makes installation faster and provides strong, dependable thread engagement.
Stud only: This listing covers the stud by itself; nuts are not included. That gives you the freedom to pair it with the exact nut grade and finish your project requires, such as ASTM A194 Grade 2H heavy hex nuts commonly specified alongside B7 studs.
Common Applications for a 5/8-11 B7 stud 4 inch
- Flanged connections in piping and pressure vessel systems
- Heavy machinery and equipment assembly
- Structural and construction fastening
- Pump, valve, and compressor mounting
- Maintenance, repair, and overhaul (MRO) where high-strength studs are required

Shipping Policy
To ensure your order is shipped safely and appropriately, we determine the shipping method based on weight, size, and handling requirements.
Parcel Shipments
Smaller items that meet standard carrier limits are shipped via common parcel carriers such as UPS, FedEx, or USPS. This is calculated for you automatically at checkout.
LTL Freight (Less-Than-Truckload)
Orders that:
Weigh over 150 lbs, or
Exceed parcel carrier size or dimensional limits
will ship via LTL freight.
LTL shipments are handled by third-party freight carriers and typically involve palletized delivery. Transit times and delivery scheduling vary depending on carrier availability, destination, and freight class.
Please note:
LTL deliveries often require a delivery appointment.
Liftgate service, limited access, or residential delivery may affect transit time and cost.
It is best to reach out to us before your purchase on items that exceed 150lbs or that are larger than 96 inches in any one direction in order to ensure that you get an accurate estimate on cost.
Full Truckload (FTL) / Specialized Freight
Large or specialized items—such as tanks, vessels, oversized equipment, or shipments requiring hazmat handling or oversized permits—are managed directly by Tri-State Supply.
These shipments may require:
Full truckload (FTL) transport
Oversized or overweight permits
Specialized carriers or equipment
Additional coordination prior to shipment
Because of this, processing and delivery timelines for full truckload or specialized freight are determined on a case-by-case basis. Our team will coordinate directly with you to confirm logistics before shipment. You will need to reach out to us for a quote. You may also arrange freight for your purchases. Loading fees, appointments, and more arrangements will still need to be agreed upon before something leaves our property.
Order Processing & Timing
Most in-stock orders are processed within 1–3 business days. Freight shipments—especially LTL and full truckload—may require additional time to schedule pickup and delivery.
Estimated delivery dates are provided as guidance and are subject to carrier and logistical factors beyond our direct control.
