AMPCO

AMPCO manufactures nonsparking tools from two primary alloys: aluminum bronze and beryllium copper. Aluminum bronze tools, such as the combination wrench model 1512, are composed of copper with aluminum and other elements, providing corrosion resistance and reduced spark risk. Beryllium copper tools, like the slotted screwdriver model S-39, contain beryllium and copper, offering higher tensile strength and hardness while remaining nonsparking. Both materials are nonferrous and do not produce sparks when struck against steel or other hard surfaces. The tools are supplied with a natural finish—no plating or coating—to maintain material integrity in chemical environments.

Based on the products stocked by 3G Electric, AMPCO impact sockets are currently available in SAE sizes, such as the 1-7/16 in socket size with a 1 in drive (model I-1D1-7/16 (4-PT)). The catalog does not list metric impact sockets from AMPCO at this time. For metric nonsparking applications, AMPCO offers combination wrenches (e.g., model 1330 in 23 mm) and open-end wrenches (e.g., model WO-22X23 in 22 mm and 23 mm). If metric impact sockets are required, please contact 3G Electric to verify current availability or alternative solutions.

AMPCO nonsparking tools are designed to reduce ignition risk in hazardous locations where flammable gases, vapors, or dusts may be present. While the tools themselves are not ATEX-certified as equipment, their material composition (aluminum bronze or beryllium copper) meets the nonsparking requirements commonly referenced in ATEX 2014/34/EU guidelines for hand tools. Users should verify that the specific tool material is compatible with the chemical environment and temperature class of the zone. For example, beryllium copper tools offer higher mechanical strength and are suitable for Zone 1 or Zone 2 areas. 3G Electric recommends consulting the site safety engineer to confirm compliance with local ATEX regulations.

AMPCO offers sockets with different drive point configurations to match fastener types. A 4-point socket, such as the impact socket model I-1D1-7/16 (4-PT), is designed for square-drive fasteners or applications requiring a positive grip on square heads. A 12-point socket provides more engagement points, allowing it to be used on hex fasteners with a 12-point profile or on standard hex bolts at multiple angles. The 12-point configuration is common in combination wrenches like model 1330, which offers flexibility in tight spaces. Both types are available in nonsparking materials from AMPCO.

No, AMPCO nonsparking screwdrivers, such as the slotted models S-39 (1/4 in tip) and S-34 (1/8 in tip), are not insulated. They are constructed from beryllium copper and are intended for use in environments where spark prevention is critical, not for protection against electric shock. The tools lack dielectric ratings and should not be used on live electrical circuits. For electrical safety, use insulated tools rated to appropriate voltage levels. AMPCO screwdrivers are designed for mechanical tasks in hazardous areas, such as adjusting valve actuators or removing covers in flammable gas zones.

3G Electric maintains an inventory of commonly requested AMPCO tools, including the models listed in the catalog. For in-stock items, orders are typically processed and shipped within 1-3 business days. For tools not in stock, lead times depend on AMPCO's production schedule and can range from 4 to 8 weeks. 3G Electric can provide estimated delivery dates upon request. The company ships globally and can arrange expedited logistics for urgent requirements. Contact 3G Electric with specific part numbers to confirm availability and lead times.
