A-LOCK AIRLOC FASTENERS

A-Lock fasteners are common to Beechcraft airplanes and latches on many cowlings. The design consists of a simple stud, with a pin pressed into the shank. The pin is installed after inserting the stud through the panel hole and removed prior to removing the stud. Some installations use a grommet in the fastener hole. Unlike other fasteners, the grommet does not usually require replacement when installing new studs. Base part numbers indicate stud diameter and head style. A-Lock studs are made in several blank lengths indicated by the first dash number in the charts. Each blank length can have up to 10 second dash numbers or grip sizes. The second dash number indicates the maximum grip range in .010² increments. Milspec primarily stocks sizes common to Beech aircraft in stainless steel for repacement purposes. To remove an A-Lock stud, simply clip or remove the pin enough to back the stud out of the hole. New pins are pressed in using special pliers, or by modifying standard vice grip pliers. Drill or cut one jaw of the vice grip to allow proper relief for the pin. If new grommets are required, a flaring tool is necessary (see below).   MS P/N Our P/N Size/Head Style Grip Total Length Price Buy 112060-1-060 04-00931 #2 Flush .051-.060 .359 $3.65 112060-1-080 04-00933 #2 Flush .071-.080 .359 $3.50 112060-1-090 04-00934 #2 Flush .081-.090 .359 $3.75 294186-1-080 04-00936 #5 Flush .071-.080 .500 $3.65 294186-1-100 04-00937 #5 Flush .091-.100 .500 $4.40 294186-2-180 04-00938 #5 Flush .171-.180 .609 $3.60 294186-2-190 04-00939 #5 Flush .181-.190 .609 $3.55 294186-2-200 04-00940 #5 Flush .191-.200 .609 $3.55 294186-2-210 04-00941 #5 Flush .201-.210 .609 $3.65 294186-2-230 04-00942 #5 Flush .220-.230 .609 $3.55 294186-2-240 04-00943 #5 Flush .231-.240 .609 $3.65 294186-2-250 04-00944 #5 Flush .241-.250 .609 $3.60 294290-1-080 04-00945 #5 Round .071-.080 .500 $3.60 294290-1-090 04-00946 #5 Round .081-.090 .500 $3.60 294920-2-170 04-00947 #5 Round .161-.170 .609 $3.60   Airloc Cross Pins Series Description Part No. Price Buy #2 293274 Stainless 04-01072 $0.82 #2 99785-2 Steel 04-01071 $0.84 #5 294185 Stainless 04-01074 $0.82   A-Lock Receptacles (Solid Receptacle) Series Rivet Spacing Solid Rec.
