DEWALT PFM3613012 Push In Thread Coupler
GENERAL INFORMATION
PUSH-IN THREAD COUPLER
Steel-to-Steel Threaded Connections
PRODUCT DESCRIPTION
Push-In Thread Couplers have one end that does not require turning threaded rod elements for placement during installation. These high-performance couplings can be ideal for applications such as mounting prefabricated hardware and hanger assemblies.
GENERAL APPLICATIONS AND USES
- Rod Hangers and Supports
- Prefabrication Connections
- Trapeze Assemblies
- Threaded Rod Extensions
- Cast-In Inserts and Anchors
- Distribution Systems / Utility Lines
- Replacement for Typical Rod Coupling Nuts
FEATURES AND BENEFITS
- Push-In thread does not require turning threaded rod elements during installation
- Cinch nut mechanism designed to eliminate thread misalignment
- Threaded rod compatibility can accept burred or oiled common standard UNC threaded rods
- Separate thread-in and push-in connection ends are designed for attaching existing anchor points to pre-fabrication assemblies
- Hex nut side enables installation with a wrench for the threaded end
- Couplers compatible with 3/8″-16 or 1/2″-13 UNC threads (threaded rods and bolts)
APPROVALS AND LISTINGS
- International Code Council, Evaluation Service (ICC-ES), ESL-1485 for steel threaded connections
- Code compliant with the 2021 IBC/IRC, 2018 IBC/IRC, 2015 IBC/IRC, and 2012 IBC/IRC
- Tested in accordance with ASTM F606/606M for static loading and in accordance with ACI 355.2/ASTM E488 and ICC-ES AC193 for seismic loading

Ultimate and Allowable Load Capacities for Push-In Thread Couplers1,2,3,4
| Ultimate and Allowable Load Capacities for Push-In Thread Couplers1,2,3,4 | ||
| Threaded Rod/Anchor Diameter in. | Tension | |
| Ultimate lbs. (kN) | Allowable lbs. (kN) | |
| 3/8 | 12,375 (55.1) | 4,125 (18.4) |
| 1/2 | 18,000 (80.1) | 6,000 (26.7) |
| 1. Allowable load capacities are calculated using an applied safety factor of 3.0 2. The tabulated allowable load capacities must be checked against the steel strength of the corresponding steel threaded insert, the lowest load level controls. 3. Allowable load capacities for 3/8-inch-diameter couplers may also be used for seismic tension loading provided the allowable values are reduced by 15 percent. 4. Allowable load capacities for the 1/2-inch-diameter couplers may also be used for seismic tension loading with no additional reduction. | ||

| Rod Diameter in. | Tension, lbs. | |||
| ASTM A36, ASTM F1554 Grade 36 Fu = 58 ksi | ASTM A307 Fu = 60 ksi | ISO 898 Class 5.8 Fu = 72.5 ksi | ASTM A193 Grade B7 Fu = 125 ksi | |

| For sI: 1 inch = 25.4 mm; 1 lbf = 0.0044 kN, 1 ksi = 6.894 MPa. 1. Allowable load used in the design must be the lesser of internally threaded coupler values and tabulated steel threaded insert values. 2. Allowable loads for steel strength are calculated using allowable tension equal to 0.33 x Fu x Anom. | ||||
