Flared Wing Ferrule Inserts

Features of Flared Wing Ferrule Inserts

• Higher Quality Flared Wing Ferrule Inserts:

  Flared Wing Anchor with UNC Threaded Socket

  
  

  The Flared Wing Ferrule Insert combines a machined, UNC-threaded ferrule with flared wings at the embedded end. The socket accepts standard bolts at the concrete face, while the wings enlarge the bearing area inside the concrete and hold the insert square during placement. Thread sizes run from 1/2"-13 to 1"-8 UNC, with a galvanized surface finish.

   

  Load Transfer and Rated Capacity

  
  

  The flared wings transfer tension from the bolt into the concrete over a larger bearing surface than a plain ferrule, spreading the load deeper into the element and resisting pullout in the thin-wall sections typical of culvert units. Reference ratings are published as ultimate mechanical capacity and as working tension and shear: the 1/2"-13 insert is rated at 2,120 lb, while the higher-capacity 3/4" version reaches 4,830 lb, with minimum edge distances from 6" to 9" and corner distances from 9" to 14". Working loads follow a 3:1 safety factor in 3,000 psi concrete with the insert set back 1/2" from the face and at least 3/4" clearance from the bottom face. Minimum insert spacing is twice the corner distance. Capacities are based on mechanical testing and available industry data. Actual performance depends on concrete strength, edge distance, spacing and full bolt engagement. The insert is not a lifting anchor; use a rated lifting system for lifting.

   

  Purpose-Built for Wing Wall and Culvert Connections

  
  

  The insert is manufactured for precast culvert and retaining wall assemblies in which a wing wall anchor connects to a concrete footing projecting laterally into backfilled soil behind the wall. Cast into the panel during production, it provides a clean, precisely positioned thread for the anchor bolt, replacing site drilling, through-bolts or chemical anchors on buried concrete.

   

  Installation, Specification and Inspection Practice

  
  

  Fix the insert to the form with the thread opening against the form face so the socket sits flush with the concrete after stripping; a locating jig or screwed plug keeps it square and keeps slurry out of the thread. Hold the published setback of 1/2" from the surface and at least 3/4" clearance from the bottom face, and maintain the minimum edge and corner distances with spacing of no less than twice the corner distance. Compact the concrete around the insert without resting vibrators on the wings. Per the catalog, do not pair plated inserts with hot-dip galvanized bolts. Factory quality control covers thread gauging, dimensional checks and tensile verification on a sampled basis, with batch test reports available on request. Confirm the bolt engages the full thread depth and that edge and backfill conditions on site match the design assumptions before loading the connection.

• Flared Wing Ferrule Inserts With Shorter Lead Time:

  

  
  

  Fabricated for a precast concrete retaining wall which forms a wing wall for a precast concrete culvert unit, the 

  Wing Wall Anchor supports a concrete footing projecting laterally from the wing wall into the back-filled soil 

  behind the wing wall.

  Plated inserts are not designed for use with hot dip galvanized bolts.

  Table is based on 3,000 psi and 145 pcf concrete.

  Inserts must be set back 1/2”from concrete surface.

  Inserts should have 3/4” minimum clearance off the bottom face to obtain rated loads.

  Below capacities are based upon mechanical testing and available industry data.

  Minimum spacing of inserts is 2 x (corner distance).

• Cost-controllable Flared Wing Ferrule Inserts:

  Clean Cast-In Threads for Buried Connections

  
  

  Bolt into a factory-positioned, load-rated thread instead of drilling through hardened concrete on site. The flared wings hold the socket square during the pour, and the thread stays clean until the anchor bolt is fitted.

  
  

  Published Ratings with a 3:1 Safety Factor

  
  

  Working tension and shear figures are published per part code, based on 3,000 psi concrete, a 1/2" setback and 3/4" bottom clearance. Design proceeds from documented data rather than guesswork.

  
  

  Durable Galvanized Finish, Full Size Range

  
  

  The galvanized finish resists corrosion in precast yards and buried service, and the range covers 1/2" to 1" UNC threads with higher-capacity wing geometries. Confirm finish pairing with the specified bolt before ordering.
