Product Specification Sheet
Steel Extension Spring
Model Number: MTM-119
The Steel Extension Spring is a closely wound laboratory spring used for experiments involving elasticity, force, extension, load, and spring behaviour. Micro Technologies supplies the spring with loops at both ends for convenient attachment to stands, hooks, mass hangers, and compatible mechanics apparatus. Manufactured from approximately 23 SWG steel wire with an approximate diameter of 6 mm, the spring provides controlled extension under applied loads. Multiple lengths are available to accommodate different experimental requirements, including 100 mm, 150 mm, and 225 mm options. Its compact construction, reusable design, and convenient mounting arrangement make it suitable for physics laboratories, universities, colleges, research facilities, laboratory equipment distributors, and institutional procurement.
Product Specification
The Steel Extension Spring is a closely wound mechanical spring intended for practical laboratory investigations involving force, extension, elasticity, and the behaviour of materials under tensile loading. Its uniform coil arrangement allows the spring to extend progressively when an appropriate load is applied, making it useful for observing the relationship between applied force and resulting displacement.
Loops are formed at both ends of the spring to provide convenient and secure attachment during experimental work. These end loops allow the spring to be connected to laboratory stands, hooks, mass hangers, or other compatible mechanics equipment without requiring complicated mounting components. The approximately 6 mm diameter provides a compact configuration suitable for common laboratory arrangements.
Micro Technologies supplies the Steel Extension Spring in several lengths to support different experimental ranges. The spring is manufactured from approximately 23 SWG steel wire, providing a useful balance between flexibility, resilience, and mechanical durability. Depending on the selected variant, different total extensions can be obtained under an average load of approximately 200 g.
The spring can be used for investigations involving Hooke's law, spring extension, elastic behaviour, applied force, load-extension relationships, and spring constant determination. Its clearly defined length and extension characteristics make it suitable for comparative experiments in which different spring configurations need to be evaluated under similar loading conditions.
For laboratories requiring frequently used mechanics accessories, the Steel Extension Spring provides a practical combination of durability, convenient handling, replaceability, and economical procurement. Its simple mechanical construction requires minimal maintenance, while the availability of multiple sizes allows buyers to select a suitable version according to experimental requirements.

FAQs
What is a Steel Extension Spring used for?
A Steel Extension Spring is used in mechanics experiments involving force, elasticity, extension, and tensile loading. It can also be incorporated into suitable setups for studying Hooke's law and spring behaviour.
What sizes are available?
The standard range includes approximately 100 mm, 150 mm, and 225 mm lengths. These variants provide different extension ranges, allowing laboratories to select a spring according to their experimental setup.
What is the spring made from?
The spring is manufactured from steel wire of approximately 23 SWG. Its closely wound construction provides the resilience and flexibility required for repeated extension experiments.
What is the diameter of the spring?
The spring diameter is approximately 6 mm. Its compact dimensions make it convenient for use with common laboratory stands, mass hangers, and mechanics apparatus.
Are loops provided at both ends?
Yes. Loops are formed at both ends to simplify mounting and attachment of loads. They allow the spring to be connected conveniently to compatible laboratory support arrangements.
Can this spring be used for Hooke's law experiments?
Yes, it can be used in suitable force-extension experiments to investigate elastic behaviour and determine the relationship between applied load and extension within the spring's usable elastic range.
Does the Steel Extension Spring require calibration?
The spring itself is generally not supplied as a calibrated measuring instrument. For quantitative experiments, known masses and calibrated measuring scales should be used to obtain reliable force and extension measurements.
How should the spring be maintained?
Keep the spring clean and dry and avoid stretching it beyond its safe elastic range. Periodically inspect the coils and end loops for permanent deformation, corrosion, or mechanical damage.
Can Steel Extension Springs be ordered in bulk?
Yes. Bulk quantities can be supplied for laboratories, universities, colleges, scientific equipment distributors, institutional projects, and procurement requirements.
Can custom spring sizes be supplied?
Custom lengths or spring configurations may be considered depending on required specifications, quantity, and manufacturing feasibility. Buyers can provide the required dimensions when requesting a quotation.
How are the springs packed for bulk supply?
Springs can be individually or collectively protected to minimize tangling and deformation during transportation. Bulk and export packaging can be arranged according to order requirements.
What is the delivery time for quantity orders?
Dispatch time depends on the selected sizes, quantity, customization, and destination. Estimated production and delivery details can be provided with the commercial quotation.
