304 Stainless Steel Nylon Tipped Socket Set Screws. Nylon tipped grub screws. Soft tip compresses into threads to become self locking. Helps to prevent shaft damage.

• Socket driven grub screws that uses a non-metallic tip made of Nylon to prevent damage to the shaft it secures.
• Ideal for joining a pulley, gear, or collar to a shaft without scratching or scarring, and the nylon tip can also provide a self-locking effect by increasing friction and absorbing vibration, preventing loosening.
