This low-profile receptacle is designed specifically for the oversized 991F-Series Camloc fasteners (we do not carry this series). The 991F Series is easily identified by the 3/8" (9.5mm) shank OD and 19/32" (15mm) long cross bar.
The 991R2-1 indicates that the receptacle is designed for permanent mounting using either 3mm screws or 1/8" rivets (not included). The AGV specifies zinc-plated steel construction. Sold individually. Studs not included.
Note: We have never carried the matching Camloc 991F Series studs. This receptacle is not compatible with any of the studs we carry.
