Hex Coupling Nuts and Hex Nut Cold Forged
Hex Coupling Nuts and Hex Nut Cold Forged A post tension bar is actually quite different from a stress bar. A post tension bar, also known as a prestressing bar, is a strong metal rod that is used in the construction of concrete structures, such as buildings, bridges, and parking garages. Post tension bars are designed to create a compressive force within the concrete that helps to counteract the tensile forces that the structure will experience over time. This can improve the integrity and ... -
Hex Thin Nut and Heavy Hex Nut
Hex Thin Nut and Heavy Hex Nut A post tension bar is a strong metal rod that is used in the construction of concrete structures such as bridges, buildings, and parking garages. Its advantage over traditional reinforcement is that it creates a compressive force within the concrete, which helps to counteract the tensile forces that the structure will experience over time. This can improve the strength, durability, and integrity of the concrete structure, making it more resistant to cracking, c... -
M36 Dome Nut for PT Bar/PC Bar
*Geotechnical *Reinforcing *Post-Tensioning * Form works *Micro piles *Ground Anchors *Soil Nailing *Tunneling*Mining M36 Dome Nut for PT Bar/PC Bar Product Introduction Primary Functions: 1. Locking Prestress: Threads onto the protruding strand end and locks against the anchor plate after tensioning, maintaining strand elongation (prestress force). 2.

Coupling Nut or Hex Coupling Nut
Coupling Nut or Hex Coupling Nut Product Introduction Primary Functions of Hex Nut: Locking Prestress: Threads onto the protruding strand end and locks against the anchor plate after tensioning, maintaining strand elongation (prestress force). Adjustment: Allows fine-tuning of strand tension during stressing (±2–5mm adjustments). Sealing: In encapsulated (unbonded) PT systems, it seals the strand end against corrosion (with grease/oil). Redundancy: Provides secondary locking if... -
HDG M32 Dome Nut for Prestressed Thread Bar / PT Bar
*Geotechnical *Reinforcing *Post-Tensioning * Form works *Micro piles *Ground Anchors *Soil Nailing *Tunneling*Mining HDG M32 Dome Nut for Prestressed Thread Bar / PT Bar Product Introduction Application of Hex Nut Common in bonded PT systems (grout provides corrosion protection). Projects with potential for re-tensioning (e.g., segmental bridges). Cost-sensitive projects where corrosion risk is moderate. Application of Dome Nut Unbonded PT systems (no grout; relies on sheathing/grease).... -
Dome Nut Hex Nut Spherical Nut for PT Bar/PC Bar
*Geotechnical *Reinforcing *Post-Tensioning * Form works *Micro piles *Ground Anchors *Soil Nailing *Tunneling*Mining Dome Nut Hex Nut Spherical Nut for PT Bar/PC Bar Product Introduction How the Nut and Plate Work Together During Stressing: Strands are tensioned by hydraulic jacks. Wedges grip the strand inside the anchor plate’s tapered hole. After Stressing: Jacks release force → wedges bite into the strand, transferring load to the anchor plate. Hex nut is immediately tighte... -
Locking Hex Nut and Nailing Nut
Locking Hex Nut and Nailing Nut Product Introduction In post-tensioning (PT) systems, hex nuts and anchor plates are critical components that work together to transfer, lock, and distribute prestressing forces from tensioned strands into concrete structures.

Fasteners And Nuts and Hex Bolts And Nuts
Fasteners And Nuts and Hex Bolts And Nuts Product Introduction Anchor Plate: Distributes prestress force into concrete and confines wedges. Hex Nut: Locks prestress, enables adjustments, and seals against corrosion. Together, they ensure PT forces are permanently, safely, and efficiently transferred to the structure—enabling thinner concrete, longer spans, and crack-free performance. Product Name Nominal Diameter Material SW H OD Hardness Weight Dome Nut (mm... -

Anchor Wedge Plates or Anchorage Wedge Plates
Anchor Wedge Plates or Anchorage Wedge Plates A threaded bar can be used as a ground anchor by drilling a hole into the ground and inserting the bar deep enough to provide sufficient stability for whatever is being anchored. This could be anything from a small tent or canopy to a large sign or billboard. The bar is typically secured in place with concrete, soil, or other materials that provide enough friction to prevent it from being pulled out of the ground by force. Depending on the weight... -
