RENY Hexagon head bolt

Overview of RENY Hexagon head bolt

RENY Hexagon head bolt are high-performance, engineering-grade fasteners made from polyamide MXD6 reinforced with 50% glass fibre, offering an excellent strength-to-weight ratio. These bolts are often used where a hex bolt or hex headed bolt is required, but where metal (e.g. stainless steel hex head bolts) may be less desirable due to weight, conductivity, or corrosion.

Product Parameters

RENY Hexagon Head Bolts typically adhere to established metric standards for hexagon head bolts, such as ISO 4014 (partially threaded) or ISO 4017 (fully threaded).

Key Features

RENY hex bolts offer a unique combination of mechanical, thermal, and electrical properties far exceeding standard nylon or polypropylene fasteners:

• Exceptional Mechanical Strength: RENY exhibits excellent tensile and flexural strength, making it comparable to some non-ferrous metal alloys. This allows the hex bolts and nuts assembly to sustain higher loads than typical plastic screws.

• Dimensional Stability: Due to low water absorption compared to commodity nylons, MXD6 maintains superior dimensional stability, which is crucial for fasteners requiring precision fits, such as specific m6 hex bolt or m8 hex bolt applications.

• Corrosion Resistance: RENY is inherently resistant to a wide range of chemicals, oils, and organic solvents, eliminating the corrosion and rust issues associated with standard metal hex bolt screw types.

• Lightweight: Being a polymer, the RENY hex head bolts offer significant weight reduction, a crucial factor in automotive and aerospace design.

• Electrical Insulation: The material is non-conductive, offering excellent electrical insulation for applications where preventing short circuits is paramount.

• Heat Resistance: It maintains its mechanical integrity over a wide temperature range, with a continuous use temperature up to 105°C (221°F).

Key RENY MXD6 – 50% Glass Fibre Reinforced Nylon Properties

Applications

The unique features of RENY position the hex bolts as the fastener of choice in demanding, specialized environments:

1. Automotive and Transportation: Used in under-the-hood applications, sensor mountings, and lightweighting initiatives where resistance to high temperatures, oil, and vibration is required.

2. Electrical and Electronics: Ideal for securing high-voltage components and circuit boards where non-conductivity is essential. It prevents issues that can arise with metallic fasteners, including certain hex socket bolt types.

3. Chemical Processing Equipment: Used in pump housings, valves, and piping where resistance to aggressive chemical agents is necessary, and where stainless steel hex head bolts might still corrode.

4. Medical Equipment: Its chemical resistance and stability make it suitable for non-magnetic or chemically sterilized equipment.

5. Construction and Civil Engineering: Utilized where a combination of high strength and long-term weather resistance is needed.

Advantages

• Lightweight: Much lighter than equivalent metal hex head bolts.

• High Strength: Thanks to glass fibre reinforcement, RENY bolts (hex or socket) are very strong for a polymer.

• Non-Corrosive & Non-Magnetic: Good for environments where corrosion or magnetism is a concern.

• Thermal Stability: Can operate continuously at ~105 °C.

• Good Flame Resistance: UL94 HB rating helps in safety-critical or regulated environments.

• Electrical Insulation: Useful in electronic and electrical assemblies.

• Low Water Absorption: Maintains dimensional stability in humid/wet conditions.

Packaging & Delivery

Standard packaging includes PE bag, foam cover, and one double-deck corrugated outer carton for safety during transit. Delivery time is 5-15 working days depending on the quantity.
