Description
The Hex Domed Cap Nut, manufactured in accordance with DIN 1587, is a premium fastening solution designed to provide protection, safety, and a refined appearance for threaded assemblies. Made from high-quality 304 or 316 stainless steel, this domed cap nut encloses the exposed end of a bolt, preventing thread damage while enhancing corrosion resistance and visual appeal.
This specific model features a left-hand (left tooth) thread, tightening counter-clockwise, making it ideal for applications where rotational forces could cause standard right-hand threads to loosen. Combining durability, precision machining, and a smooth domed finish, the Hex Domed Cap Nut is widely used in furniture assembly, machinery, automotive components, and architectural installations where both functionality and aesthetics are critical.
Features & Benefits
- Enhanced Safety and Aesthetics: The domed, closed design of this cap nut covers sharp bolt ends, preventing injuries and creating a smooth, finished appearance.
- Corrosion Resistance: Made from high-quality 304 or 316 stainless steel, these nuts are highly resistant to rust and oxidation, making them suitable for use in both humid and outdoor environments.
- Specialized Left-Hand Thread: This specific Hex Domed Cap Nut is available with a left tooth or left-hand thread, which tightens by turning counter-clockwise. This feature is crucial for specific mechanical applications where standard right-hand threads could loosen due to rotational forces.
- Durable and Standardized: Manufactured to the DIN1587 standard, this nut guarantees consistent dimensions and reliable performance. The robust material and precise threading ensure a secure, slip-resistant hold.

FAQ:
Q1: What is the purpose of a hex domed cap nut?
A: A hex domed cap nut protects exposed bolt threads, improves safety by covering sharp ends, and provides a clean, finished appearance to assemblies.
Q2: What does "Left Tooth" mean for a Hex Domed Cap Nut?
A: "Left Tooth" refers to a left-hand thread. Unlike a standard nut that tightens clockwise, this nut tightens by turning it counter-clockwise. This is typically used on shafts that rotate clockwise to prevent the nut from spinning off during operation.
Q3: Should I choose 304 or 316 stainless steel?
A: 304 Grade is excellent for most general-purpose applications where cost and standard corrosion resistance are priorities.
316 Grade is recommended if the fastener will be exposed to salt spray, harsh chemicals, or marine environments, as it is among the best corrosion resistant screws and nuts available.
Q4: Does the dome offer any mechanical strength?
A: While the dome is primarily for protection and aesthetics, the hex base and precision threading provide the same high-strength clamping force as a standard industrial hex nut.
Q5: Can these nuts rust?
A: While stainless steel is highly resistant, it is not completely rust-proof. If the passive protective layer is damaged or if the wrong grade is used in a high-chloride environment, surface staining or pitting can occur.
