Taper Allen Socket Plug

Taper Allen Socket Plug - A4 Stainless DIN 906

Taper plugs seal via metal-to-metal wedging of male and female thread patterns. Headless stainless steel plug style, no sealing washer required.

Consider using a thread sealant on the plug prior to installation to achieve adequate seal and to reduce the possibility of leakage.

Specification

DIN 906 tapered hexagon socket screw plugs with a hexagon socket drive at one end and a slightly tapered pipe thread along the full length of the plug. The threaded section of the plug is slightly conical and when tightened to the appropriate torque, the deformation of the threads creates the seal.

Designed to create a tighter seal for masking threaded holes and is commonly used to seal holes in machinery, fittings or pipes to prevent leakage of air, steam, gases, water, oil and fluids.

This plug is also great for blocking off intake manifold water ports, water pump ports, water temp and oil sender holes, engine block holes, etc.

Material: A4 / SAE Type 316 

A4 / 316 Stainless Steel fasteners are "marine grade" corrosion resistant; suitable for salt water applications. A4 fasteners also offer increased resistance to chemicals when compared with A2 stainless fasteners.

Per DIN EN ISO 3506: A4-50 austenitic stainless steel specifically refers to a tensile strength of at least 500 N/mm2.

Commonly used in wet environments. Popular across a wide range of industries: automotive, agriculture, photographic, medical / surgical,  food processing, clean energy, etc.
