Key Features

✅ Nickel-Plated Finish

• Corrosion Resistance: Protects against humidity, chemicals, and oxidation for indoor/outdoor use.
• Smooth Surface: Reduces friction and galling during installation.

✅ Flat Head Slotted Design

• Low Profile: Sits flush with surfaces to avoid interference in tight spaces.
• Slotted Drive: Compatible with standard flat-head screwdrivers for easy manual installation.

✅ Half-Threaded Step Shoulder

• Unthreaded Shoulder: Provides a precise bearing surface for bushings, bearings, or pivoting components.
• Controlled Engagement: Threads only partially engage, reducing stress on materials like plastics or thin metals.

✅ Durable Alloy Steel Core

• Grade 8.8/10.9: High tensile strength (up to 1,000 MPa) for heavy-load applications.
• Heat-Treated: Hardened for wear resistance and repeated use.

✅ RoHS Compliance

• Lead-Free: Safe for electronics, medical devices, and consumer goods.
