Description
Monster Overview:
Fix your project right the first time with 3/8-16 Serrated Hex Washer Taptite Alternative Screws from Monster Bolts. Engineered for heavy-duty assemblies in sheet metal, steel plate, and softer alloys, these tri-lobular thread-rolling fasteners cut clean internal threads while their built-in serrated washer head locks against vibration.
The case-hardened steel body receives a CR+3 zinc plating, is bake-relieved to remove hydrogen embrittlement, and is top-coated with a dry-film wax for smoother drive-in and added corrosion protection. Fully RoHS compliant, they ship fast from our Florida warehouse with industry-leading customer support.
Monster Features:
- Self-Threading Power: Tri-lobular Taptite-style point forms threads in untapped holes without chips.
- Vibration Grip: Integral serrated washer flange bites into the mating surface to resist loosening.
- Smooth Assembly: Zinc bake + wax finish lowers friction and improves corrosion resistance.
- Full Thread (Tap Bolt): Maximizes grip length and pull-out strength.
- Bulk Savings: Reduce cost per unit—ideal for production lines and MRO teams.
