Description
Monster Overview:
Perfect for electronics housings and thin sheet-metal work, #4-40 × 5⁄16″ Phillips Flat-Head Taptite Alternative Screws form clean internal threads as they drive—no tapping, no chips. The 82° countersunk head seats flush for snag-free surfaces, while corrosion-resistant 18-8 (304) stainless steel delivers long-term durability in demanding environments.
After machining, each screw is chemically passivated to remove free iron and topped with a factory-applied dry-film wax that lowers installation torque by up to 30 %. Fully RoHS compliant and shipped fast from our Florida warehouse with monster-grade support.
Monster Features:
- Self-Threading Power: Taptite-style tri-lobular point taps its own threads—no pre-tap, no chips.
- 18-8 Stainless Steel: Austenitic, non-magnetic alloy offers outstanding corrosion resistance.
- Passivated + Wax: Passivation removes free iron; dry-film wax lowers friction for smoother assembly.
- Flush 82° Flat Head: Countersunk head ensures a smooth, snag-free finish.
- Single Size: 5⁄16″ overall length—fully threaded for maximum grip in thin materials.
