Provides convenient means for accurately locating rivet holes with .750 inch spacing relative to stud mounting hole. Ollgaard et al. [ 1] proposed an empirical formula for the load-slip curve of conventional welded stud connectors under continuous loading: Previous researchers have proposed various definitions for the shear stiffness prediction of welded stud connectors. Oehlers and Coughlan [ 2] proposed an empirical equation to calculate the initial shear stiffness of normal stud connectors based on the experimental results, as shown in Equation ( 4). It is adopted by Shim et al. [ 16] to evaluate the shear stiffness of large diameter studs, and the results show that Equation ( 4) gives rather conservative predictions:

Snap retaining ring under cross pin using needle nose pliers, then rotate retaining ring 180° until GB 50017 [ 23] provides Equation ( 3) to estimate the shear strength of welded stud connectors: where is the characteristic compressive strength of concrete prisms (MPa) and other variables have the same meaning with Equation ( 1). In GB 50017 [ 23], the resistance factor or the partial factor for the shear strength of welded stud connectors is not clearly specified. To be used as a guide only. To obtain optimum performance, final hole size should be determined for Plus flush head styles and solid retaining rings. 2700 Series. Flush head styles and split retaining

turn fasteners are qualified to MIL-F-5591* specifications. Also included are receptacles for fast installation, or In Equations ( 4) and ( 5), represents the initial shear stiffness of welded stud connectors defined as the ratio of half of the shear strength to the corresponding slip (N/mm); is the shear strength of welded stud connectors (N); is the cylinder compressive strength of concrete (MPa), which could be taken as 59.8 MPa based on the relationship between the cylinder compressive strength and the cube compressive strength proposed by Mansur and Islam [ 25]; is the diameter of the stud shank (mm); stands for the elastic modulus of concrete (MPa), which could be regarded as 37.6 GPa predicted by proposed by EN 1992-1-1; and is the elastic modulus of the stud material (MPa) which is equal to 2.0 × 10 5 MPa.

Drill, counterbore, and then tap thread in structure using data from table below. Turn KEENSERTS Insert into tapped holedamage. Select the ejector spring corresponding to stud assembly series selected. See table for part numbers. Both the 30 mm stud and the high strength stud exceed the limitation of current design codes, so the applicability of the existing design equations to large diameter and high strength studs need to be evaluated. In AASHTO LRFD [ 19], the design strength of one stud connector can be determined by the following equation: where is the nominal shear strength of the welded stud connector (N), is the cross-sectional area of stud shank (mm 2), is the elastic modulus of concrete (MPa), is the characteristic cylinder compressive strength of concrete (MPa), the nominal tensile strength of welded studs is 415 MPa, and the resistance factor for welded stud connectors equals 0.85. Provides for retraction of stud assembly to allow opening and closing of equipment without the possibility of jamming or

In Equations ( 6) and ( 7), is the cylinder compressive strength of concrete which is equal to 59.8 MPa and stands for the diameter of the stud shank (mm). Maximum Service Temperatures: Stainless Steel—700°F; Steel and Bryllium Copper—450°F. Retaining Rings (for 2600/2700 Series) In Equations ( 8) and ( 9), is the slip value of welded stud connectors (mm) and stands for the ratio of the loading force to the shear strength of welded stud connectors. for ultrasonic installation. Integral stud cup protects top panel surface from abrasion. 2600 Series.Ultimate tensile strength: 300 lbs. Working strength: 200 lbs. Stud grip increments: .030 inch. For other styles, select stud dash number, then subtract seven dash numbers. Requires .438 diameter installation hole.
