Nuts & Bolts

At CFixings we supply an extensive selection of nuts, bolts, and fasteners designed for everything from DIY projects to the most demanding industrial environments. Our range is trusted by professionals in engineering, metal fabrication, steel frame construction, and general building.

We stock a wide variety of sizes, strengths, and finishes to ensure you have the right fastener for every project.

Our Nuts & Bolts Range Includes:

Hexagon Set Screws (Fully Threaded)

Fully threaded bolts for maximum grip and secure fastening.
Applications: Engineering projects, metal fabrication, machinery assembly, structural steelwork.
Benefits: Full threading allows for flexible adjustment and high-strength fastening.

Hexagon Bolts (Part Threaded)

Strong bolts with a smooth shank section for superior clamping force.
Applications: Steel frame construction, heavy engineering, timber-to-metal joints, fabrication projects.
Benefits: Higher shear strength, ideal for load-bearing connections.

High Tensile Fixings. Grades 8.8, 10.9 & 12.9

Our high tensile fixings are designed for applications requiring superior strength, reliability, and resistance to extreme stress. These bolts are manufactured from hardened alloy steels and are commonly used in engineering, steel construction, and heavy machinery.

Grade 8.8 High Tensile Bolts & Fixings

One of the most widely used grades for structural and engineering purposes.

Applications: Steel frames, metal fabrication, machinery assembly, construction projects.

Features: Medium carbon steel, quenched and tempered; high strength with excellent wear resistance.

Benefits: Ideal for general structural applications requiring reliable tensile strength and durability.

Grade 10.9 High Tensile Bolts & Fixings

Designed for high-performance applications where greater strength is essential.

Applications: Heavy machinery, automotive assemblies, high-load structural connections.

Features: Alloy steel, quenched and tempered for extra hardness.

Benefits: Higher tensile strength than Grade 8.8, suitable for demanding mechanical stress and load-bearing environments.

Grade 12.9 High Tensile Bolts & Fixings

Engineered for the highest strength requirements in the most extreme applications.

Applications: Critical engineering structures, hydraulic machinery, heavy industrial equipment, automotive engines, motorsport applications.

Features: Alloy steel, heavily hardened and tempered for maximum tensile strength.

Benefits: Highest tensile rating in common fasteners; exceptional resistance to stretching, shearing, and breaking under extreme loads.

Key Features Across All Grades:

Precision-engineered threads for secure fastening

Available in multiple finishes: BZP, Self Colour, Black, Galvanised, Stainless A2 & A4

Supplied in a variety of lengths and diameters

Fully tested and certified for industrial use

Designed for extreme strength and durability in high-stress applications.
Applications: Structural steel construction, metal frameworks, plant machinery, bridges, and heavy equipment.
Benefits: Outstanding tensile strength, certified for engineering-grade use.

Multiple Finishes Available. Choose the right finish for your application:

BZP (Bright Zinc Plated): For clean appearance and light corrosion resistance — great for indoor or sheltered areas.

Self Colour: Uncoated finish for general use, can be painted or coated.

Galvanised: Heavy-duty corrosion protection, ideal for external steel structures and exposed metalwork.

Black: Industrial black oxide finish for both visual appeal and mild corrosion protection.

Stainless Steel A2: Corrosion-resistant, suitable for outdoor and fabrication environments.

Stainless Steel A4 (Marine Grade): Excellent for marine, coastal, or chemical environments requiring high corrosion resistance.

Additional Bolts Available:

Coach Bolts (Carriage Bolts): Ideal for timber construction and structural woodwork.

Socket Head Cap Screws: Precision bolts for metal fabrication, machinery, and engineering assemblies.

Flange Bolts: Integrated washer head for even load distribution on metal components.

U-Bolts: Perfect for pipework, steel supports, and tube clamping in fabrication.

Anchor Bolts: For securing steelwork, machinery bases, and structural frames to concrete.

Eye Bolts: Used in lifting, securing steel components, and structural tie-downs.

T-Head Bolts: Common in machine tool slots, framework assembly, and specialised steelwork.

Wide Selection of Nuts:

Hex Nuts: Standard fastening solution for structural steel and machinery.

Nyloc Nuts (Lock Nuts): Vibration-resistant, ideal for machinery and steel structures.

Wing Nuts: Quick adjustment fasteners for temporary steel or metal fixtures.

Dome Nuts (Cap Nuts): Aesthetic finish with thread protection for visible steelwork.

Flange Nuts: Built-in washer for securing metalwork under heavy loads.

Square Nuts: Traditional style for vintage machinery or specialist metalwork.

Coupling Nuts: Long nuts for connecting threaded rods in steel frames or metal fabrication.
