Screw

Screw

Overview

A screw is a type of fastener featuring a helical ridge (thread) wrapped around a cylindrical shaft. Screws are designed to hold materials together securely, offering greater holding power than nails due to their threaded design. In picture framing, screws are commonly used to attach hanging hardware, secure backing boards, or assemble frame components.

Types and Uses in Framing

• Wood Screws: Ideal for attaching hardware to wooden frames or backing boards.
• Machine Screws: Used with nuts or tapped holes, often for metal frame assembly.
• Self-Tapping Screws: Can penetrate soft metals or plastics without pre-drilling.
• Decorative Screws: Sometimes used for exposed hardware that contributes to the frame's aesthetic.

Best Practices

• Pre-drill holes when working with hardwoods to avoid splitting.
• Use screws of appropriate length to secure hardware without puncturing artwork.
• Choose rust-resistant or stainless-steel screws for long-term durability, especially in high-humidity environments.
• Match screw head types (flat, pan, or countersunk) to hardware requirements.
