The Vista Rangemaster Hex Key Set is the one you want if you shoot a Mathews Solocam or Mission-Archery bow.
The Rangemaster Hex Drive Key Set has eight different keys in Imperial sizes 5/64 through 7/32 inch (7/32", 3/16", 5/32", 9/64", 1/8" , 7/64", 3/32", 5/64") to fit all the grub screws and hex drive bolts on most bows. The 7/32 will fit Mathews and Mission limb bolts on bows built prior to 2009 (The new bows use the industry standard 3/16 inch limb bolts).
Vista Rangemaster comes in a tough plastic fold-up holder.
This set of Allan keys from Pine Ridge archery contains the same nine keys (in Imperial sizes 5/64 through 3/16 inch) as the economy Allen key set shown below, but this one has a plastic handle that is a little more secure.
This is the last set of Allen keys you'll ever have to buy. Features include heavy-duty one-piece construction with a slip-resistant finish firmly held together with a custom bolt and nut assembly, which means no loose and floppy tools. This Allen wrench set is made in the USA from high-quality 8650 industrial-strength chrome-vanadium tool steel that has been hardened so the keys won't round off.
This handy and inexpensive Allan wrench set belongs in every archer's kit bag or tool box. This basic hex-drive key set has nine different keys in Imperial sizes .050 through 3/16 inch, to fit all the grub screws and hex drive bolts on most bows, in a rugged fold-up holder, at very economical price.
This little Allan Key Set is a must-have tool for every archery kit box.
Sooner or later every compound bow shooter will encounter a bow with a rounded-out or stripped grub screw. This is most common with limb bolts where someone has attempted to adjust the draw weight using the wrong size Allen wrench.
There is no easy fix for this situation but your local jeweler or watchmaker may be able to help. A well-equipped jeweler will have a miniature slot cutter that they can use to convert your ruined grub screw to a regular slotted screw, easily removed or adjusted with a normal screw driver.
