The Socket Head Cap Screw 1/4 UNC 1/2" (2pcs) is a useful pack of 2x 1/4" thread size UNC bolts with Allen key caps. These bolts are ideal for attaching dovetails to telescope tube rings and clamshells via the universally recognised Whitworth photographic thread. At 3/4" length, these bolts provides enough length and reach for connecting mounting hardware to medium-sized instruments. Larger and heavier telescopes may require longer bolts. Those with narrower clamshell-design mounting rings, such as the Coronado and TeleVue systems should be directed towards the shorter 1/2" (SOCA144) bolts, in order to prevent grounding and damage to the telescope's tube. If unsure of your particular needs, please contact Telescope House for clarification.
