Square Bend Screw Hooks / L-Hooks (Zinc Plated, Stainless Steel) – Shoulder & Plain Type – Manufacturer Direct

Versatile Square Bend Screw Hooks (L-Hooks): The Organizer’s Choice

At Handan Bolt, we manufacture a wide variety of Square Bend Screw Hooks, widely recognized in the hardware industry as L-Hooks due to their distinct 90-degree right-angle shape. Produced in our state-of-the-art facility in Yongnian, China, these hooks are a staple for hardware wholesalers, home improvement retailers, and industrial suppliers. Unlike rounded cup hooks, the open “L” shape allows for items to be mounted and removed with zero resistance, making them the ultimate solution for quick-access storage.

What is an L-Hook?

An L-Hook is a specific type of Screw (Read more on Wikipedia) fastener. It features a threaded shank with a sharp gimlet point for driving into wood, and a non-threaded shaft that bends at a sharp 90-degree angle. This design creates a secure ledge for hanging items. We offer these hooks in two primary structural designs:

• With Shoulder (Self-Stop): These hooks feature a small disc or “shoulder” at the transition between the screw thread and the smooth shaft.
  
  Advantage: The shoulder acts as a stop washer, preventing you from over-screwing the hook and ensuring it sits perfectly flush and stable against the wall or wood.
• Non-Shoulder (Plain): The thread continues up the shaft without a stop flange.
  
  Advantage: These offer more flexibility in depth adjustment and are typically more economical for bulk industrial applications.
• With Safety Buckle (Q-Hanger): We also manufacture advanced versions with a spring-loaded buckle to prevent items from falling off in high winds (ideal for outdoor string lights).

Material Specifications

To ensure our hooks perform in every environment, we manufacture them in several material grades:

1. Carbon Steel (Zinc Plated)

This is the industry standard. Our hooks are made from high-quality carbon steel wire and finished with a durable Blue/White or Yellow Zinc coating. This plating provides a shiny, clean appearance and essential rust protection for indoor use in garages, basements, and kitchens.

2. Stainless Steel (304 / 316)

For outdoor decks, patios, or marine applications, rust is not an option. Our Stainless Steel L-Hooks offer lifetime corrosion resistance, making them perfect for hanging exterior decorations or tools in humid environments.

3. Brass (Solid or Plated)

For a decorative touch, we offer Solid Brass L-Hooks. These are popular in interior design for hanging keys, jewelry, or picture frames where the hardware needs to look elegant.

Applications: Why Use an L-Hook?

The “L” shape offers unique advantages over the traditional “C” or “Question Mark” shape:

• Key Holders: The straight arm allows keys to slide on and off instantly without getting snagged.
• Tool Organization: Perfect for pegboards or wooden tool walls to hold wrenches, hammers, and paintbrushes.
• Retail Displays: Used extensively to display packaged goods that have a hanging slot.
• Curtain Rods: Larger L-hooks can serve as simple, minimalist brackets for lightweight curtain rods.

Installation Guide

Installing our Square Hooks is straightforward:

1. Mark: Use a pencil to mark the desired location.
2. Pilot Hole: For hardwoods (like oak) or when using thick hooks (larger than 4mm), drill a small pilot hole to prevent the wood from splitting. Softwoods (like pine) usually don’t need this.
3. Twist: Insert the sharp point and twist clockwise. The leverage provided by the “L” arm makes hand-tightening easy.
