Model: K333
Classification: Lock Key / Accessory
Compliance: UL FTTA2 / FTTA8 Category 1
Product Overview
The K333 is a nickel-plated steel key with a glass-fiber reinforced nylon handle, manufactured for use in cabinet lock and enclosure locking systems that require custom multi-combination key profiles. It is designed as an accessory component for pin-tumbler lock cylinders including the I-9346 series, supporting individual key, keyed-alike, and master key configurations.
The handle is molded from PA66 reinforced with 30% glass fiber, selected for its dimensional stability, impact resistance, and resistance to creep under sustained grip load — properties that standard unreinforced nylon does not reliably provide in industrial use.
Construction Details
Key Body
- Base material: Steel
- Surface treatment: Nickel plating
- Function: Engages pin stack in compatible lock cylinder
- Corrosion performance: Nickel plating provides effective barrier against oxidation in standard industrial environments
- Dimensional accuracy: Critical for consistent pin stack engagement and smooth rotation across cylinder service life
Handle
- Material: PA66 + 30% glass fiber (GF30)
- Color: Black
- Mechanical properties of PA66 GF30:
| Property | Value |
| Tensile Strength | ~180 MPa |
| Flexural Modulus | ~9,000 MPa |
| Impact Resistance | High vs unreinforced PA66 |
| Operating Temperature | −40°C to +120°C |
| Chemical Resistance | Good against oils, greases, fuels |
| UV Resistance | Moderate — black pigment provides some UV stabilization |
