At JM Hardware®, we pride ourselves on being a leading timber bolt manufacturer, delivering high-quality timber bolts for construction, landscaping, and heavy-duty applications. Timber bolts, also known as dome head bolts or mushroom head bolts, are specifically designed for wood-to-wood and wood-to-metal connections, providing superior strength and durability. Whether you need standard or custom timber bolts, our comprehensive range of products, advanced manufacturing processes, and dedication to quality ensure that we meet the unique needs of B2B buyers across industries.
What Are Timber Bolts?
Timber bolts, often referred to by other names depending on the region or application, include:
-
Dome Head Bolts
-
Mushroom Head Bolts
-
Oval Head Bolts
-
Economy Bolts
-
Fender Bolts
Timber bolts feature a large, rounded, low-profile head designed to distribute load evenly across wooden surfaces. The square or finned shank under the head prevents the bolt from spinning during installation, making it ideal for securing large timber pieces.
Materials Used in Timber Bolt Manufacturing
As a professional As a professional timber bolt manufacturer, we use premium materials to ensure durability, reliability, and compatibility with various environmental conditions:
-
Carbon Steel:
The most common material for general-purpose timber bolts, offering strength and cost-efficiency.
-
Stainless Steel (SS304, SS316):
Ideal for environments exposed to moisture or harsh weather, such as marine or outdoor applications, due to its corrosion resistance.
-
Galvanized Steel:
Hot-dip galvanized bolts are widely used for outdoor timber applications, providing excellent corrosion resistance against moisture and rust.
-
Silicon Bronze:
Used for decorative or specialized applications where corrosion resistance and aesthetic appeal are critical.
-
High-Strength Alloy Steel:
Suitable for applications requiring additional load-bearing capacity and mechanical strength.
Surface Finishes for Timber Bolts
To enhance the longevity and performance of our timber bolts, we offer a wide range of surface coatings and finishes:
-
Zinc Plating:
Offers basic rust protection, suitable for indoor or low-humidity environments.
-
Hot-Dip Galvanizing:
Provides a thick, durable coating for corrosion resistance in outdoor and marine environments.
-
Teflon Coating:
Reduces friction during installation and provides protection against chemicals.
-
Black Oxide Coating:
Adds a professional, sleek appearance with moderate corrosion resistance.
-
Epoxy Coating:
Ideal for bolts used in chemically exposed or high-moisture conditions, offering extended durability.
-
Passivation:
Enhances the corrosion resistance of stainless steel bolts.
Applications of Timber Bolts
Our timber bolts are specifically designed for wood applications where strength and longevity are critical. Some of the most common applications include:
-
Timber Construction
Connecting beams, planks, and posts in wooden structures such as bridges, piers, and pergolas.
-
Deck Building
Securing deck boards and joists in residential and commercial decking projects.
-
Landscaping
Reinforcing retaining walls, fences, and large landscaping timbers.
-
Utility Pole Connections
Fastening cross arms and structural components in utility poles.
-
Playgrounds and Parks
Securing wooden equipment and outdoor furniture in public areas.
-
Heavy Timber Structures
Fastening beams in barns, warehouses, and other heavy wooden constructions.
-
Marine Applications
Securing docks, piers, and waterfront structures exposed to saltwater.
-
Custom Wooden Projects
Crafting wooden furniture, large sculptures, or other unique wooden installations.
Grades and Standards of Timber Bolts
Our timber bolts are manufactured to meet a variety of industry standards, ensuring consistency, safety, and performance. Common grades and standards include:
-
DIN 603
European standards for carriage bolts, which are often similar in application to timber bolts.
-
ASTM A307
For general-purpose bolts used in construction and timber projects.
-
ISO 898
Standards for bolts with controlled mechanical properties, including tensile strength and hardness.
-
ASTM A193 B7
For high-strength applications requiring durability under stress.
-
SAE J429
5. Standards for automotive and heavy-duty equipment fasteners.
-
AS/NZS 1214

Unique Features of Timber Bolts
1.Large, Rounded Heads: Distribute load over a wider area to prevent wood splitting or crushing.
2.Square or Finned Shank: Keeps the bolt stable during installation by preventing rotation.
3.Corrosion-Resistant Coatings: Extends lifespan in outdoor and marine environments.
4.Customizable Lengths: Available in both standard and custom sizes for unique projects.
Testing Methods for Timber Bolts
As a leading timber bolt manufacturer,we ensure that every product meets the highest quality standards. Our rigorous testing methods include:
-
Tensile Strength Testing:
Verifies the bolt’s ability to withstand applied forces without failure.
-
Corrosion Resistance Testing:
Salt spray tests are conducted to evaluate performance in humid or coastal environments.
-
Load Testing:
Simulates real-world conditions to assess the bolt’s load-bearing performance.
-
Dimensional Inspection:
Verifies the accuracy of size, thread, and shank design to ensure proper fit.
-
Impact Testing:
Ensures the bolt’s structural integrity under sudden force or pressure.
-
Hardness Testing:
Ensures the material meets the required hardness levels for durability.
Manufacturing Process of Timber Bolts
Our advanced production processes as a timber bolt manufacturer ensure top-quality products:
-
Material Selection:
Premium materials are carefully sourced to meet specific strength and environmental requirements.
-
Cold or Hot Forging
Heads are forged to ensure structural integrity and durability.
-
