VELCRO® Brand hook fasteners come in two main types, woven and molded. Woven hooks are flexible and easy to sew, while molded hooks are strong, durable, and low-profile. Each type offers unique material options, strength levels, and temperature ratings for industrial, OEM, or DIY use.
Overview of VELCRO® Brand Hook Types
VELCRO® Brand hook fasteners are part of the hook-and-loop system that lets two sides attach and release repeatedly. The “hook” side has tiny plastic hooks that grip into soft fabric loops, forming a strong yet reclosable bond.
There are two major categories of VELCRO® Brand hooks:
- Woven Hooks – Made from nylon, polyester, or specialty fibers. These are soft, flexible, and easy to sew or heat-seal.
- Molded Hooks – Made from molded plastics like nylon or polypropylene. These offer high performance, precise hook shapes, and long cycle life.
Each type is engineered for specific conditions such as heat, moisture, fire resistance, or outdoor durability. Industrial users and OEMs often choose molded hooks for repeatable strength and clean design, while DIYers and crafters often prefer woven hooks for fabric projects and easy application.
VELCRO® Brand hooks are used across industries from aerospace and automotive to marine, uniforms, and medical devices. Every model (like Hook 88 or HTH 805) is designed to meet strict performance and temperature standards.

Choosing the Right Hook Type for Your Application
If you’re new to VELCRO® Brand fasteners, choosing the right hook type can seem confusing at first. Each hook style has a specific purpose, and picking the right one ensures your fastener works well and lasts longer. Here’s how to make the best choice step by step:
1. Match Hook Type to Loop Material
Every hook needs a loop side to work.
- Woven hooks pair best with soft woven loops like Loop 1000 or Loop 3610. These combinations are great for fabric-based projects, uniforms, and sewing.
- Molded hooks work better with brushed or knit loops that can handle firmer grip and repeated openings, ideal for straps, panels, or mounting pads.
2. Consider Temperature and Moisture Resistance
Think about where your fastener will be used: indoors, outdoors, in hot areas, or near water.
- For everyday indoor use, standard nylon hooks (like Hook 88) work perfectly.
- For high-heat or fire-sensitive areas, use Hook 66 (HI-AIR®) made from NOMEX® fibers for fire resistance.
- For marine or wet environments, Hook 81 (polyester) resists moisture and salt corrosion better than nylon.
3. Evaluate Cycle Life and Application Stress
Cycle life means how many times you can open and close the fastener before it wears out.
- High-cycle woven hooks (like Hook 65) are made for things that need to open and close hundreds or thousands of times.
- Molded hooks (like HTH 805) have consistent performance and resist fatigue, making them ideal for straps or reusable mounts.
4. Choose Stocked vs. Custom Order
Some VELCRO® Brand hooks, like Hook 88 and Hook 66, are kept in stock and ready to ship. Other specialized types such as HTH 889 (fire-rated molded) or HTH 833 (low-profile) may require a custom order due to unique materials or thicknesses.
If your project has specific requirements (like flammability rating or color matching), check with a VELCRO® Brand distributor such as iTapeStore before buying in bulk.
5. Think About Attachment Method
How you plan to attach the hook matters.
- Sew-on hooks (woven) are great for fabrics and uniforms.
- Adhesive-backed hooks (molded) stick easily to metal, glass, or plastic.
- Weldable or heat-sealable hooks are designed for vinyl or plastic surfaces.
6. Check for Compliance or Special Ratings
Some hooks are made for industries with strict safety standards:
- Fire-retardant (FR) versions for aerospace or uniforms
- Marine-grade hooks for saltwater exposure
- MIL-SPEC hooks for defense and aviation
These features ensure performance and compliance in demanding environments.
Woven hooks are the classic VELCRO® Brand hook style. They’re made by weaving tiny hook fibers into a flexible nylon or polyester fabric. This creates a strong yet soft material that can be sewn, heat-sealed, or bonded to other fabrics.
Because they are made from fiber rather than molded plastic, woven hooks bend easily, resist fraying, and work well on curved or flexible surfaces. They are commonly used for textiles, uniforms, upholstery, and soft goods.
Below are the most common woven hook fasteners and what each one is best for.

Molded Hook Fasteners
Molded hooks are made from plastic resins that are injection-molded into precise hook shapes rather than woven from fibers. This gives them a clean, uniform surface with consistent performance, even under heavy use.
They are ideal for industrial, OEM, and product design applications where strength, repeatable closure, and thin profile are important. Molded hooks are also perfect for adhesive-backed fasteners used on smooth or rigid surfaces like plastic, glass, and metal.
Unlike woven hooks, molded hooks don’t fray and can handle higher temperatures or chemicals, depending on the resin type. They’re available in nylon, polypropylene, polyethylene, or fire-retardant blends, with different hook shapes to control grip strength.
Below are the most common molded VELCRO® Brand hook types and their best uses.

How to Select the Right VELCRO® Hook Type
Choosing the correct VELCRO® Brand hook ensures your fastener performs well, lasts longer, and suits your project or production environment. The selection depends on several key factors: the surface, temperature, environment, and how often the fastener will be opened and closed.
Below is a simple step-by-step guide you can use to find the best match.
1. Identify Your Application Type
Start by thinking about what you’re fastening. Are you attaching fabric, plastic, metal, or something else?
- Fabric or textile surfaces: Use woven hooks (like Hook 88 or 65)
- Hard or smooth surfaces: Use molded hooks (like HTH 805 or 888).
The material determines how well the hooks will grip and whether you’ll need sewing, adhesive, or heat bonding.
2. Check Environmental Conditions
Where the fastener will live matters.
- High heat or flame exposure: Choose Hook 66 (HI-AIR®) or HTH 889 (FR ONE-WRAP®).
- Wet or outdoor use: Go with Hook 81 (polyester) or HTH 830 (polypropylene) for moisture resistance.
- Everyday indoor use: Hook 88 or HTH 805 are reliable all-rounders.
Different materials react differently to moisture and heat so matching the environment ensures lasting performance.
3. Consider Frequency of Use
The more often the hook is opened and closed, the more wear it will face.
- Frequent fastening: Pick Hook 65 (high-cycle woven) or HTH 745 (high-cycle molded).
- Occasional fastening: Standard hooks like Hook 88 or HTH 805 are ideal.
If your application involves daily use, high-cycle hooks offer better long-term reliability.
4. Choose Attachment Method
How you plan to attach the hook determines which product to buy:
- Sew-on: Use woven hooks like Hook 88, Hook 65, or Hook 66.
- Adhesive-backed: Choose molded hooks such as HTH 805 or HTH 888.
- Heat-sealable or weldable: Use special coated hooks (available upon request).
The wrong attachment method can weaken adhesion or damage your surface, so always match the hook base to your installation method.
5. Verify Any Safety or Industry Standards
If you’re working on regulated products (like aerospace, defense, or fire gear), choose hooks that meet MIL-SPEC or FAA standards, such as Hook 66 or Hook 46. These meet strict testing for flame, heat, and chemical resistance.
FAQ
