| Coil Shape / Spring Type | |||
| Your choices are... | |||
| Barrel | The spring is shaped like a barrel with diameter at the two ends and a larger diameter in the middle. | ||
| Conical | Conical springs have a large diameter and one end that taper to a smaller diameter at the other. Conical springs have a smaller height when compressed than straight coil springs due to the nesting of the coils. Batter springs are a common application of conical springs. | ||
| Cross-section Compression (Garter, Meander, etc.) | Cross-section compression springs are designed to be compressed perpendicular to the coil axis as opposed to along the axis in traditional compression springs. Cross-section compression springs may be designed in straight, continuous lengths, or in round shapes for installation in a groove. Types of cross-section compression springs include canted coil springs, garter springs, meander springs, and helical seal springs. Cross-section compression springs are used to spring load the lip in seals and are sometimes referred to as seal energizing springs. | ||
| Hourglass | Hourglass springs have a larger diameter at the two ends and a reduced diameter in the middle. | ||
| Straight | Straight-shaped compression springs are a standard coil type. Other coil types are hourglass, conical, and barrel types. | ||
| Other / Specialty | Other, unlisted, or specialty compression spring type. | ||

| Material: | |||
| Your choices are... | |||
| Alloy Steel (Music Wire) | The spring is manufactured from music wire, or other alloy steel. Music wire is a high-carbon steel, small diameter wire that is commonly used for springs. Music wire is also known as ASTM A228. | ||
| Brass | The spring is manufactured from brass. Brass has good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties, and low magnetic permeability. | ||
| Composite | The spring is manufactured from a composite plastic material. A composite is a solid material comprised of two or more substances that have distinct properties. When merged, each substance retains its own characteristics while imparting the entire composition with beneficial properties. For example, a plastic material in which a fibrous framework is embedded for greater structural stability. | ||
| Copper Base Alloy | The spring is manufactured from a copper base alloy. Copper base alloy springs are specified for services where superior corrosion resistance and electrical conductivity qualities are desired. All copper-base alloys are easily plated, brazed, soldered, and machined. | ||
| Hard Drawn | The spring is manufactured from hard drawn wire. Hard drawn wire is an inexpensive, carbon steel wire used for low stress applications. Hard drawn wire is also known as ASTM A227. | ||
| High Carbon Steel Wire | The spring is manufactured from high carbon steel. High carbon, hard drawn steel is used when resistance to abrasion and impact is required. | ||
| Nickel Base Alloy Wire | The spring is manufactured from a nickel base alloy. | ||
| Stainless Steel | The spring is manufactured from stainless steel. Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings. | ||
| Other | Other, unlisted, or proprietary material. | ||

| |||
| End Configuration | |||
| Your choices are... | |||
| Closed / Squared Ends | The ends of the compression springs where pitch of the end coil is reduced so that the end coils touch. | ||
| Ground Ends | The end is ground to provide a flat plane. | ||

| |||
| Die Spring | Die springs are helical compression springs generally of rectangular section. They can carry roughly 30% more load for the same deflection than can be carried by a round section. They are not solely used in dies but find application in clutches, brakes, farm machinery, and aircraft mechanisms. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
