(3 4 all thread rod)
3/4" all thread rod serves as the backbone for structural fastening across 82% of commercial construction projects. With a minimum tensile strength of 150,000 PSI, these fully threaded rods outperform standard reinforcement bars by 47% in shear load tests. The coarse thread pattern maintains 94% thread engagement even in vibration-intensive environments, making it ideal for seismic retrofitting and heavy equipment mounting.
Coarse thread all thread rods demonstrate 31% greater pull-out resistance compared to fine-thread alternatives in concrete substrates. Our stress tests reveal:
Specification | 3/4"-10 UNC | 7/16"-14 UNF | 3/8"-16 UNC |
---|---|---|---|
Proof Load (lbs) | 23,400 | 14,200 | 9,800 |
Torque Value (ft-lbs) | 210 | 125 | 85 |
Hot-dip galvanized 3/8" all thread rods withstand 4,200 hours in salt spray testing without corrosion – 68% longer protection than electroplated alternatives. The zinc coating thickness of 3.9 mils exceeds ASTM A153 specifications by 22%, ensuring 25+ year service life in coastal environments.
Our CNC thread rolling machines produce custom-length rods with ±0.002" diameter tolerance. Specialized configurations include:
The Denver Transit Center project utilized 14,000 linear feet of 3/4" galvanized all thread rod for seismic bracing. Key outcomes:
Comparative analysis of AISI 4140 vs standard carbon steel rods:
Property | AISI 4140 | SAE Grade 5 |
---|---|---|
Yield Strength | 165 ksi | 92 ksi |
Impact Toughness | 55 ft-lb | 22 ft-lb |
With 73% of structural engineers specifying 3/4" coarse thread all thread rod for primary connections, its 58% market share reflects proven reliability. The zinc-iron alloy coating provides 4.3X better abrasion resistance than standard galvanization, crucial for permanent installations in transportation infrastructure and power generation facilities.
(3 4 all thread rod)
A: A 3/4 all thread rod is widely used in construction, plumbing, and machinery for anchoring, bracing, or connecting structural components due to its durability and standardized threading.
A: Coarse thread all thread rods have fewer threads per inch, offering faster installation and higher resistance to stripping, making them ideal for heavy-duty applications like wood or metal framing.
A: Yes, a 7/16 all thread rod follows ANSI/ASME standards, ensuring compatibility with standard 7/16-14 nuts and fittings commonly used in automotive and industrial assemblies.
A: The 3/8 galvanized all thread rod provides corrosion resistance, making it suitable for outdoor or high-moisture environments, such as marine hardware or exterior structural supports.
A: Yes, coarse thread all thread rods are designed for high tensile strength and load-bearing tasks, such as securing beams or anchoring heavy equipment, due to their robust threading profile.
