It needs to be a larger screw/thread-size to be strong enough for bulk-fill and tank-block conversions. It also makes a nice upgrade for use with 12 gram CO cartridges for improved stability and to center the transfer port better. This screw was designed by Magnum Airpower and custom manufactured from heat-treated 410 stainless steel to meet metric class 12.9 with a specified hardness of HRc 39-43. The approximate tensile strength is 185,000 PSI. The screw head fits the hole in the tube perfectly for improved strength, stability and port alignment. It fits a T10 Torx-drive socket. The head is .270" diameter and .065" thick, it sits just below flush so it doesn't interfere with mounting a trigger group, stock, and barrel bands can slip right over it. The original factory valve-screw is 6-40 x 1/8". You need to drill the screw-hole in the valve about 3/32" deeper and tap it to 8-32 thread. A bottoming-tap is required to cut the threads close to the bottom of the hole so the head of the screw can seat flush against the valve. Drilling through into the valve-throat is a common practice also, it makes tapping the hole a lot easier and doesn't effect performance to a noticeable degree. It's strong enough to safely allow bulk-fill and tank-block conversions with tanks regulated up to 1400 PSI with a 1.8K burst disc. For HiPAC, SafePAC, dummy CO2 cartridges and cartridge eliminators the limit is 3000 PSI or whatever pressure the maker of those parts says is safe. Those devices lower the force applied to the valve-screw because they have a very small outlet diameter, one of these custom screws is all that's needed. Any PCP or HPA conversion that pressurizes the tube to more than 1100 PSI requires a 1.8K burst disc for the tube pressure to be safe. More pressure than that requires two extra valve-screws to be added to the side-positions in PCP-valve fashion. Three of these screws installed correctly can handle up to 3000 PSI of pressure on the valve.
