Description
Monster Overview:
Perfect for electronics, sheet-metal, and precision assemblies, #4-40 Phillips Flat-Head Taptite Alternative Screws from Monster Bolts form their own internal threads as they drive—no chips, no pre-tapping. The 82° countersunk head seats flush for snag-free surfaces, while the tri-lobular point delivers reliable thread rolling in steel, aluminum, and plastics.
Every case-hardened steel screw receives a CR+3 clear-zinc coating, is bake-relieved to eliminate hydrogen embrittlement, and is top-coated with a factory dry-film wax that lowers driving torque and adds a second barrier against corrosion. Fully RoHS compliant, they ship fast from our Florida warehouse with monster-grade support.
Monster Features:
- Self-Threading Power: Taptite-style tri-lobular point taps its own threads—no broken taps or chips.
- Flush 82° Flat Head: Countersunk head delivers smooth, snag-free assemblies.
- Zinc Bake + Wax: CR+3 clear zinc with bake relief and dry-film wax lowers friction and fights corrosion.
- Phillips Drive: #1 Phillips recess for precise, slip-resistant installation.
- Full Thread (Tap-Bolt): Every stocked length is fully threaded for maximum grip depth.
