Impact sockets

Impact sockets serve fastening and loosening operations for bolts and nuts in industrial environments, especially when using high-torque, high-speed power wrenches. This product range includes drive sizes from 1/4 inch to 2.1/2 inch, with hexagon sizes from 4mm to 160mm, meeting diverse technical requirements. Manufacturing material is primarily Chrome Vanadium or Chrome Vanadium Molybdenum alloy, with black phosphate surface coating to increase durability and corrosion resistance.

The design features a safety pin hole and rubber ring groove on the socket body to prevent detachment from the drive shaft during high-speed operation. Product lines from ELORA Germany and Alkitronic comply with DIN 3121 and ISO 1174 standards, ensuring dimensional accuracy and load-bearing capacity. Suitable for use with air impact wrenches, torque multipliers, or hydraulic torque wrenches in mechanical assembly, heavy equipment maintenance, and automotive repair. Vinatools distributes genuine products with clear warranty.

Classification by drive size

Drive size determines the torque transmission capacity and application range of impact sockets. Small drive sizes suit precision work, while large drive sizes meet the needs of tightening large bolts with high torque. Selecting the correct drive size optimizes work efficiency and extends tool life.

The 1/4 inch drive line includes 788 and 796-E, serving light-duty applications with hexagon sizes from 4mm to 14mm. The 3/8 inch drive such as 789, 789MG, and 789IN expands the hexagon range up to 22mm, suitable for automotive repair and medium equipment assembly. The 1/2 inch line with 790, 790MG, and 790LT meets common industrial needs, with hexagon sizes from 8mm to 36mm.

The 3/4 inch drive such as 791, 791IN, and 791LT serves heavy-duty work with hexagon sizes up to 50mm. The 1 inch line includes 792, 792IN, and 792LT withstanding very high torque, with hexagon sizes from 22mm to 80mm. The 1.1/2 inch drive such as 793, 793LT, and 793A is designed for heavy-duty equipment, with hexagon sizes from 30mm to 95mm.

Technical specifications and materials

The manufacturing material of impact sockets directly affects durability and load-bearing capacity. Chrome Vanadium alloy provides high hardness and good wear resistance. Some premium lines use Chrome Vanadium Molybdenum to increase toughness, reducing the risk of cracking under continuous impact.

The black phosphate surface coating not only creates the distinctive color but also protects the metal from corrosion in humid environments or chemical exposure. This coating also helps reduce friction during assembly and disassembly. The safety pin hole design on the socket body allows secure attachment to the machine drive, preventing the socket from flying off during high-speed operation.

The rubber ring groove around the drive square holds the rubber retaining ring, increasing stability when transmitting torque. Products such as 31420 and 31421 provide safety accessories for 1.1/2 inch drive. DIN 3121 and ISO 1174 standards ensure drive square dimensions are compatible with common power wrenches on the market.

Product lines by length

The length of impact sockets affects the ability to access bolts in tight spaces or deep positions. Standard product lines have lengths suitable for most common applications. Long lines are designed for cases where nuts are located deep or require greater working distance.

Codes such as 790A-5-8S belong to the short type, optimized for limited space and reduced weight during operation. Long lines include 790A-5-8L, 790LT, and 791LT extending reach up to 110mm, suitable when bolts are located deep within machinery structures.

The Alkitronic group provides codes with lengths of 90mm and 110mm such as 31451, 31471, 31452, and 31472. Increased length helps access difficult positions but also increases deflection when transmitting torque, requiring consideration when selecting.

Internal hexagon and star sockets

Internal hexagon sockets serve bolts with internal hexagon holes, commonly found in precision equipment and structures requiring high aesthetics. The external hexagon design on the socket fits tightly into the internal hexagon hole of the bolt, transmitting torque effectively without damaging the outer surface.

The internal hexagon line includes 790IN, 789IN, 791IN, and 792IN with drive sizes from 3/8 inch to 1 inch. Alkitronic codes such as 31017 and 31019 provide 24mm and 30mm internal hexagon sizes for 1.1/2 inch drive.

Star sockets such as 797-E, 798-E, and 796-E serve star-shaped screws, common in electronics and automotive industries. The star design distributes force evenly across multiple contact points, reducing the risk of rounding screw corners when tightening.

Magnetic sockets

Sockets with integrated magnets help hold bolts or nuts securely during assembly, especially useful when working at height or in tight spaces. The magnet prevents bolts from falling out of the socket when moving or positioning, increasing work speed and reducing loss of small parts.

The magnetic product line includes 789MG with 3/8 inch drive and 790MG with 1/2 inch drive. Both lines feature 6-point hexagon, suitable for frequent repair and maintenance applications. The magnetic force is strong enough to hold bolts but does not affect the ability to remove when needed.

When using magnetic sockets, care should be taken to avoid contact with sensitive electronic equipment or environments requiring non-magnetic conditions. The manufacturing material maintains the same durability as standard impact sockets, ensuring resistance to high torque when operating power wrenches.

Stabi-H and Stabi-S systems

The Stabi system combines Stabi-H sockets and Stabi-S hexagon bits, creating a flexible solution for multiple bolt sizes. Stabi-H serves as the main body with drive square connecting to the power wrench, while Stabi-S is the replaceable hexagon bit that can be changed according to the bolt size to be tightened.

Stabi sets for 1.1/2 inch drive include 31015, 31016, 31018, 31020, 31021, 31022, 31023, 31024, and 31025 with hexagon sizes from 19mm to 55mm. The 1 inch drive has sets such as 31010, 31011, and 31012 serving 22mm, 24mm, and 27mm hexagon sizes. The 3/4 inch drive has 31001 for 12mm hexagon. Each Stabi set comes with rubber rings and safety pins to secure components during operation.
