The heavy-duty 40-Series Camloc fasteners are rated for 700 pounds working strength (1050 pounds ultimate strength). The Philips (cross) head allows quick use with a standard Phillips #2 screwdriver (no special tools needed). The 40-Series are easily identified by the 3/8" diameter head (smaller Camloc 27-Series Studs have a 1/4" diameter head). Each stud assembly includes the stud, crosspin, barrel, and spring. Sold individually.

The 40-Series studs are designed to be used with a metal grommet (Part Nos. 6081, 6082, or 6083, sold separately) to help spread the attachment forces. The large diameter grommet (Part No. 6082) is recommended for soft materials such as fiberglass.

The dash number is normally stamped on the head of the stud. The dash number corresponds to overall stud length using the following formulae:

Dash number = (Length - 0.62) / 0.03
Length = (Dash number * 0.03) + 0.62

Total Grip is the total thickness of the panels to be fastened. When using the 40 Series Side Mount Receptacle (Part No. 6087), measure from the front of the removeable panel to the top of the receptacle and subtract 0.06". When using the 40 Series Floating Receptacle (Part No. CAM244-16), use the next longer stud. Add 0.026" to the grip length when using the Standard Grommet, or add 0.050" to the grip length when using the Large Diameter Grommet.

* Longer studs (-16 and up) should use the Camloc 40 Series Split Ring Retainer (Part No. 6075, sold separately) to retain the stud in the grommet. Shorter studs (-14 and less) do not need to use this retainer.
