Description
Engineered for strength and reliable performance, the Thread Rolling Screws Torx Flat Head Steel Zinc & Waxed Tri-Lobe #4-40 x 3/8 are designed as a high-quality alternative to Taptite screws. The combination of thread-rolling construction, zinc finish, and a waxed coating delivers durable threads, low friction, and a clean flush finish in a variety of thin-material assemblies.
