The Snap-on Tools Universal Swivel Chrome Socket 3/8" Drive 19mm 6 Point (FSUM19) is a specialty tool designed for loosening and tightening 19mm metric nuts and bolts in confined spaces and at awkward angles. Here's a breakdown of its features and potential applications:

Features:

• Drive size: 3/8" - This refers to the square opening that fits onto a 3/8" drive ratchet or extension, ideal for tight spaces where a larger drive size might not fit.
• Socket size: 19mm - This indicates the diameter (across flats) of the metric nut or bolt head the socket is designed to grip.
• 6-point design: The socket has 6 contact points on the inside that grip the fastener. This provides a strong grip and helps prevent rounding off corners of the nut or bolt head, particularly important when working at angles.
• Universal swivel mechanism: This allows the socket head to swivel on its axis through a significant range of motion, providing access to fasteners at angles where a straight socket wouldn't fit.
• Chrome finish (likely): The socket likely has a chrome plating for corrosion resistance and easier cleaning.

Benefits:

• Access fasteners in tight spaces and at awkward angles: The combination of the 3/8" drive size and swivel mechanism allows you to maneuver the socket into difficult-to-reach locations, especially valuable for working on vehicles or machinery.
• Strong grip: The 6-point design ensures a secure grip on the fastener, reducing the risk of slippage or rounding off corners.
• Increased efficiency: By contorting the socket instead of yourself or moving other components, you can work more efficiently, especially in confined areas.
• Durability: Snap-on tools are known for their high-quality construction, and the FSUM19 is likely made from strong steel for long-lasting use.

Applications:

This socket is ideal for professional mechanics or serious DIYers who encounter situations requiring access to 19mm metric nuts and bolts in tight spaces and at awkward angles, common scenarios include:

• Engine repairs: Many fasteners within the engine compartment, especially near the firewall or behind components, might be difficult to reach with a straight socket. The FSUM19's swivel mechanism allows access at angles.
• Body repairs: Certain areas on the vehicle's body panels or frame might have 19mm nuts or bolts in tight locations where this socket's maneuverability can be beneficial.
• Suspension components: Reaching some nuts or bolts on suspension parts, especially near the engine compartment or wheel wells, can be challenging. The FSUM19's swivel mechanism can help reach these fasteners.
• General repairs: This socket can be helpful for various situations where you encounter 19mm metric nuts and bolts in confined spaces or at awkward angles on machinery, appliances, or other equipment.
