Our Stainless Steel Torque Hinge SFTH-05-58

Sugatsune America’s stainless steel torque hinge SFTH-05-58 is a compact, non-adjustable friction hinge engineered for controlled movement in lids, access panels, covers, and other components that require stable positioning throughout the hinge’s operating range. The SFTH-05-58 allows engineers, fabricators, and architectural hardware specifiers to incorporate torque control without significantly altering the look or mounting style of a conventional hinge.

The friction torque hinge SFTH-05-58 provides a torque rating of 50.3 lbs·in per piece, making it the highest-torque model in Sugatsune’s SFTH series. This fixed torque helps hold panels and covers in position instead of allowing them to swing freely, drop suddenly, or require secondary support hardware in suitable applications. Because the hinge is non-adjustable, the SFTH-05-58 should be selected after evaluating panel weight, center of gravity, hinge quantity, mounting orientation, and desired operating feel.

Built from 304-grade stainless steel, the SFTH-05-58 is well-suited for demanding environments where corrosion resistance, long service life, and consistent operation are important. Its clean, simple profile makes it useful for both industrial assemblies and architectural applications where exposed hardware must remain functional, durable, and visually refined.

A Heavy-Duty Friction Torque Hinge for Controlled Panel Movement

The stainless steel torque hinge SFTH-05-58 is designed to provide friction resistance across a nearly 180° opening angle. This allows lids and covers to remain stable at various positions within the hinge’s range of motion, depending on application conditions and installation requirements.

In industrial settings, this can support safer, cleaner, and more controlled access to internal components. Equipment covers, inspection panels, machine guards, and horizontal enclosure doors often require frequent opening and closing. A friction torque hinge can help reduce uncontrolled movement and improve usability without requiring a separate stay, catch, or prop in every design.

Stainless Steel Construction for Industrial and Architectural Environments

The SFTH-05-58 is constructed from stainless steel to provide durability in applications exposed to moisture, frequent handling, cleaning processes, or more demanding environmental conditions. Stainless steel hardware is often specified where long-term performance and corrosion resistance are priorities, particularly in equipment, marine, transportation, commercial interiors, and specialized facility environments.

This model has an operating temperature range of -4°F to 140°F (-20°C to 60°C), supporting use in a wide range of indoor and outdoor applications. Engineers should still evaluate the full operating environment, including chemical exposure, washdown conditions, vibration, cycle frequency, and load requirements, before specifying the hinge.

Because Sugatsune America serves both architectural and industrial markets, the SFTH-05-58 can be considered for projects where technical performance and finished appearance both matter. It is particularly useful when the application requires the strength and corrosion resistance of stainless steel along with the controlled motion of a torque hinge.

Where the SFTH-05-58 Is Commonly Specified

The stainless steel torque hinge SFTH-05-58 may be appropriate for a range of engineered assemblies and architectural hardware applications, including:

• Industrial equipment covers
• Sheet metal access panels
• Machine guards and inspection lids
• Electrical or mechanical enclosures
• Specialty cabinetry and casework
• Marine and transportation equipment
• Commercial fixtures and service panels
• Medical or laboratory equipment where durable hardware is required
• Outdoor or semi-exposed panels within the hinge’s environmental limits

The hinge’s high torque rating makes it especially useful for heavier panels in the SFTH series. For smaller or lighter panels, engineers may consider lower-torque SFTH models to avoid excessive resistance or an overly stiff operating feel.

Explore the SFTH Series of Stainless Steel Torque Hinges

The SFTH series gives engineers and specifiers multiple fixed-torque options in the same general hinge family. Since the series is non-adjustable, selecting the correct model is essential. Torque requirements should be calculated or tested based on the panel’s dimensions, weight, center of gravity, mounting position, and number of hinges used. Torque = ½ x weight of the panel x measurement of door lid from the hinge side

The SFTH-05-58 is the strongest model in this series, offering the highest resistance for applications that require heavier covers or panels to be held with greater force. For applications that require a lighter operating feel, a lower-torque model may be more appropriate.

Specifying the SFTH-05-58 for Your Application

Because the friction torque hinge SFTH-05-58 provides fixed, non-adjustable torque, proper specification is important. Before selecting this hinge, confirm that your application is for an upward-opening lid or panel and note the following application details:

• Panel or lid weight
• Panel dimensions
• Center of gravity
• Number of hinges required
• Mounting direction and orientation
• Required opening angle
• Operating temperature
• Exposure to moisture, cleaning agents, or corrosive conditions
• Desired resistance and user operating force

FAQs

How does the SFTH-05-58 compare to other hinges in the SFTH series?

The stainless steel torque hinge SFTH-05-58 has the highest torque rating in the SFTH series, at 50.3 lb ·in per piece. This makes it suitable for heavier lids, covers, and panels than the SFTH-02-5, SFTH-03-9, SFTH-03-19, or SFTH-05-35. However, the highest torque model is not always the correct choice. Smaller panels or lighter covers may require a lower-torque hinge for smoother operation.

Is the torque adjustable on the SFTH-05-58?

No. The SFTH-05-58 is a non-adjustable friction-torque hinge with a fixed torque rating of 50.3 lb ·in per piece. If the application requires a different resistance level, Sugatsune offers other SFTH series models with lower torque ratings. Torque should be evaluated before specification to ensure the hinge meets the panel's weight, geometry, and movement requirements.

Can the SFTH-05-58 be used for both architectural and industrial applications?

Yes. The friction torque hinge SFTH-05-58 can be used in both industrial and architectural applications when the project requires controlled panel movement and can benefit from its stainless steel construction. It is especially well suited for industrial equipment covers, access panels, enclosures, and other equipment assemblies. Still, it may also be used in architectural casework, commercial fixtures, and marine interiors where corrosion resistance and controlled positioning are required. Make sure to use the correct fasteners depending on your application.

What types of panels are best suited for the SFTH-05-58?

The SFTH-05-58 is best suited for panels, covers, or lids that require greater holding resistance than smaller SFTH models can provide. Common examples include equipment access covers, sheet metal panels, machine guards, and service panel lids. The exact fit depends on the panel’s size, weight, center of gravity, and hinge placement.

When should I contact Sugatsune America before specifying this hinge?

Contact Sugatsune America’s Inside Sales team if you are unsure which torque rating is appropriate, if the panel has unusual dimensions, or if the hinge will be used in a demanding industrial, marine, outdoor, or specialty architectural environment. Sugatsune can help review product information and guide you toward the right torque hinge for your application.
