The KUPO KS-187 is a set of two steel hex socket cap screws with 3/8"-16 thread and a corrected 30 mm threaded length. The cap-screw head gives a deeper hex drive and a more substantial bearing surface than low-profile screw styles.
Why It Matters
Accessory and clamp assemblies sometimes need a screw that feels positive under a hex key, especially when a connection is removed and reinstalled often. KS-187 is a compact replacement set for those stronger 3/8"-16 fastening points.
