Door Handle Screws
Door handle screws are specialized fasteners used to secure door handles, levers, and associated mechanisms to doors. They differ from common screws in several key aspects due to the stresses and aesthetic requirements of door hardware.
Material
- Steel: The most common material, offering strength and durability. Often coated for corrosion resistance.
- Carbon Steel: Provides high strength but is susceptible to rust if not coated.
- Stainless Steel: Offers excellent corrosion resistance, ideal for exterior doors or high-humidity environments. Grades 304 and 316 are common.
- Brass: Used for decorative purposes and in antique or high-end applications. Offers corrosion resistance, but is softer than steel.
- Bronze: Similar to brass in appearance and application, offering corrosion resistance and a traditional aesthetic.
Purpose
The primary purpose is to firmly attach the door handle assembly to the door itself, ensuring reliable operation of the latch and locking mechanisms. They must withstand repeated use and torque forces without loosening or stripping.
Function
- Shear Strength: Resist forces applied perpendicular to the screw axis, preventing the handle from pulling away from the door.
- Tensile Strength: Resist forces applied along the screw axis, preventing the screw from stretching and failing.
- Corrosion Resistance: Protect against rust and degradation, ensuring long-term functionality.
- Aesthetic Integration: Often designed to match the finish and style of the door handle.
Usage Scenarios
- Interior Doors: Standard steel screws are typically sufficient.
- Exterior Doors: Stainless steel screws are recommended due to exposure to weather.
- High-Traffic Doors: Higher-grade steel or stainless steel screws are preferred for increased durability.
- Security Doors: Specialized screws with tamper-resistant heads may be used.
- New Installations: Used when installing new door handles and locking mechanisms.
- Replacements: Used to replace damaged or worn screws.
Common Types
- Machine Screws: These screws have a consistent diameter along their length and are often used with threaded holes in the door handle rose or escutcheon plate. They typically have a flat or pan head.
- Wood Screws: Designed to tap their own threads into wood doors. They have a tapered shank and a variety of head styles.
- Set Screws: Used to secure handles to a shaft, often with a headless design.
- Security Screws: Feature unique head designs (e.g., Torx with a pin, one-way screws) to prevent unauthorized removal.
- Rose Screws: Short, flat-head screws specifically designed for securing roses or escutcheon plates to the door.
- Chicago Screws: Used to attach decorative or multiple pieces together.
- Tamper-Resistant Screws: Designed with special heads that require specialized tools for removal, enhancing security.
Head Styles
- Flat Head: Sits flush with the surface when installed.
- Pan Head: Slightly rounded head, providing a wider bearing surface.
- Oval Head: Combines the aesthetic of a flat head with a decorative appearance.
- Round Head: Offers a more decorative appearance.
- Button Head: A low-profile, rounded head.
Drive Types
- Phillips: Common, self-centering drive.
- Slotted: Simple, but prone to cam-out.
- Torx: Provides superior torque transmission and resistance to cam-out.
- Square (Robertson): Offers good torque transmission and resistance to cam-out.
- Hex (Allen): Requires an Allen wrench for installation.
