Overview
This screw refill kit is intended for building or replacing gun screws to the dimensions a specific job requires. It is designed for use with a matching die, along with a file and either a drill press or pin vise, when custom thread length, overall length, or head thickness is needed. The blanks are made from easy-to-thread, tough forging steel, and the kit includes 20 No. 4 head blanks with a 0.220" outside diameter. It is a practical option for careful bench work where a tailored fit matters more than a ready-made fastener.

Considerations & Trade-offs
- Requires a die with the correct threads, plus a file and either a drill press or a pin vise, so it is a shop-use item rather than a ready-to-install screw set.
- The blanks are supplied with a common shank length and are meant to be cut and finished to the needed dimensions, which adds setup and finishing time.
- If a hard-wearing surface is desired after threading, the description notes a separate surface hardening compound is needed; that step is not included in the kit.
- The kit includes multiple head sizes, so the No. 4 head blanks are only one part of the assortment rather than a dedicated single-size pack.
