Monster Bolts – Bulk 1/4-20 Phillips Flat Undercut Taptite Alternative Screws

Monster Overview:

Fix your project right the first time with 1/4-20 Phillips Flat-Head Undercut Taptite Alternative Screws from Monster Bolts. The tri-lobular thread-rolling point forms clean internal threads as it drives—eliminating chips and the need for taps—while the 82° undercut flat head seats flush and preserves extra thread engagement in thin sheet metal.

Each case-hardened steel screw receives a CR+3 zinc plating, is bake-relieved to remove hydrogen embrittlement, and is top-coated with a dry-film wax that lowers drive torque and adds corrosion protection. Fully RoHS compliant, they ship quickly from our Florida warehouse with industry-leading support.

Monster Features:

  • Self-Threading Power: Taptite-style tri-lobular point taps its own threads—no pre-tapping, no chips.
  • Undercut Flat Head: 82° countersunk head with undercut shank provides flush seating while retaining more thread depth in thin materials.
  • Zinc Bake + Wax: CR+3 clear zinc with bake relief and dry-film wax lowers friction and resists corrosion.
  • Phillips Drive: #3 Phillips recess for fast, slip-resistant installation.
  • Full Thread (Tap-Bolt): Every stocked length is fully threaded for maximum grip depth.
