Description
Monster Overview:
Miniature plastics require miniature muscle. #4-24 × 1/4" Slotted Indented Hex Washer Head Type 25 Thread-Cutting Screws from Monster Bolts carve their own coarse threads in drilled holes—so they seat with less drive torque and keep delicate plastics and composites crack-free. Zip them in with a 5/32" socket or nut-driver for maximum torque, or use the straight slot when hex access is tight.
Each screw is zinc-plated, then bake-treated to relieve hydrogen embrittlement, delivering dependable indoor corrosion protection while staying fully RoHS compliant. Orders ship fast from our U.S. warehouse and are backed by industry-leading support.
Monster Features:
- Type 25 Point: Cuts clean, gripping threads without splitting plastic.
- Slotted Indented Hex Washer Head: Micro hex drive for high torque, plus a straight slot for screwdriver access.
- Integrated Washer: Spreads load and protects the work surface—no separate washer needed.
- Zinc-Bake Finish: Zinc coating with post-bake treatment for embrittlement relief and durability.
- Low Drive Torque: Self-threading action eases installation and extends tool life.
