2600/2700 Series General Purpose 1/4-Turns.
A wide choice of general purpose studs and receptacles are available with this series. Certain 2600 and 2700 series
1/4-turn fasteners are qualified to MIL-F-5591* specifications. Also included are receptacles for fast installation, or
for ultrasonic installation. Integral stud cup protects top panel surface from abrasion. 2600 Series.
Plus flush head styles and solid retaining rings. 
2700 Series. Flush head styles and split retaining
ring. Specifications: Ultimate tensile strength: 300 lbs.
Working strength: 200 lbs *Meets the design, physical and performance requirements of MIL- F-5591. However,
full mechanical properties testing may not be performed on each production lot. 
Retaining
rings are used with stud lengths -5 and greater, except for snap-in versions which do not require retaining rings. 
Ordering Information
Note: Receptacles determine which stud is selected, therefore, an overview is included here.
To Select Stud Part Number. 1. Stud part number varies with receptacle used.
The receptacle must be chosen before selecting stud part number. See receptacle detail on Pages A-27
through A-30. 2. Determine “G” thickness as shown in drawings below. 
Important
Note: If the total thickness “G” is very near the top of the thickness range, selection of the next greater dash number
is recommended. For the other materials and for “G” thickness greater than those tabulated, contact the Camloc Products
Division. Notes: a) Increase “G” to allow for thickness of paint or other finishes and for the
compressed thickness of any b) ”G” must be increased for the following “special” conditions:
| “Special” Condition | Increase “G” Thickness |
| 212-12B Series receptacles installed | Add .038 inch |
| Front mounting receptacle (P/N 26R41-1-1AA) installed | Allow .022 inch for receptacles top side protrusion |
| Rear mounting receptacle (P/N 26R45-1-1AA) installed | Allow .018 inch for receptacle top side protrusion |
| Clip-on receptacle (P/N 99R11) installed | Add .090 and subtract 7 dash numbers |
| Single hole mounting receptacle (P/Nos. 99R10 and 99E10) | Add .020 inch |
| KNQ2 Series. Keenserts installed | Add .030 inch |
- Locate “G” total thickness in the tables with each stud.
- Then find the corresponding stud part number in the column
designated for the selected receptacle. Example 1. Stud Assembly Used: 2700-[ ] “G” Total Thickness =
.275 inch Receptacle Used: 212-12AD Stud Dash Number From Table: -9 Complete Part Number: 2700-9 Example
2. Stud Assembly Used: 2600-[ ] “G” Total Thickness =.163 inch Receptacle Used: 212-12BR Required
Calculation: “G” + .038 = .163 + .038 = .201 Stud Dash Number Selected From Table: -6 Complete Part Number: 2600-6S

Retaining Rings (for 2600/2700 Series)
Solid rings are used to hold stud assemblies stationary to the top panel. Split ring allows stud assemblies to move
freely within the top panel.
Notes: 1. Order separately.
2. Retaining rings are required for stud length dash numbers “5” and greater.
3. Studs with smaller dash numbers are self-captivating and retaining rings are not

Special Purpose Receptacles
KEENSERTS® Insert
For use in aluminum and magnesium castings and other thick materials.
Installation:
Drill, counterbore, and then tap thread in structure using data from table below. Turn KEENSERTS Insert into tapped hole
using installation tool P/N TQ-2A
for positive depth control. Drive locking kees down into the tapped threads of the structure using tool P/N TQ-2B. This
provides a positive mechanical lock against rotation.

Removal: In the unlikely event it becomes necessary to remove the
KEENSERT Insert, simply drill to the indicated depth, deflect the locking kees inward and break them off.
Then remove insert with an E-Z out type tool. An identical insert can now be installed in the original hole without
rework.
Single Hole Mounting Receptacles Designed to allow mounting in dimpled or drilled and countersink
holes. Can also be installed in tapped holes. Blind end version is ideal when receptacle is to be used with structural
foams.

Panel Preparation and Installation Data
2600 Series Protruding Head Studs
Determine panel thickness “P” and form through hole to corresponding “X” diameter. Note: Panels with thicknesses greater
than .125 inch must be back counterbored to a concentric .375 inch diameter with a remaining maximum material thickness
of .125 inch. Use split style retaining rings with back counterbore.
| P | X Dia. Ref. |
| .030 to .065 | .257 |
| .066 to .125 | .281 |
Float:
To provide float for stud assembly, increase “X” diamater to .312 inch. This hole diameter allows “P” thickness to be
increased to .187 inch without back counterboring. Larger hole requires used of solid retaining ring, P/N 2600-LW.
2600/2700 Series Snap-in Studs
Form through hole to .260-.256 diameter. Note: Panels with panel thicknesses greater than .078 must be back counterbored
