Description

Monster Overview:
Eliminate rust worries and speed assembly with 3/8-16 Unslotted Indented Hex Washer Head Thread-Cutting Screws, Type 23, 18-8 Stainless from Monster Bolts. The unslotted hex drive takes a standard 9/16″ socket or wrench for maximum torque transfer, while the integrated washer head spreads load without a separate flat washer. A Type 23 triangular chip-relief pocket at the tip clears swarf as it cuts—reducing drive torque and leaving cleaner internal threads than straight-slotted or lobed points.
Precision-machined from non-magnetic, food-safe 18-8 (A2) stainless, these screws thrive in marine, outdoor, and wash-down environments with no plating to chip or peel. All lengths are fully threaded—simply choose the size you need from the drop-down above.
Monster Features:
- Unslotted Hex Drive: 9/16″ across-flats hex resists cam-out and installs fast with common sockets.
- Integrated Washer Head: Indented hex washer head distributes clamp load without extra hardware.
- Type 23 Cutting Point: Triangular chip pocket ejects debris for smoother cutting & lower drive torque.
- 18-8 Stainless Steel: Long-term corrosion resistance—no coating required.
- Monster Quality: Tight tolerances, batch inspection, and rapid U.S. shipping.
