Hex Socket Sealing Screws 304 Stainless Steel Allen Head Rubber O Ring IP67 For Junction Box Assembly

China Suppliers Factory Hex Socket Sealing Screws 304 Stainless Steel Allen Head O-Ring IP67 for Junction Box

Hex socket sealing screws are designed for reliability and durability, featuring an Allen drive and a rubber ring beneath the head. When tightened, the rubber compresses to create an effective barrier against water and dust, eliminating the need for additional sealants. Rated IP67 and IP68, these screws are resistant to harsh environments. Available from various suppliers, including top manufacturers in China, our stainless steel and zinc-plated options ensure longevity. The hex socket head design fits perfectly in tight spaces, making them ideal for applications where a Phillips driver cannot reach. Choose our sealing screws for superior protection and quality from a trusted factory

Product Details

Allen drive makes the difference

Most sealing screws use a Phillips head. These use a hex socket. You drive them with an Allen key. Why does that matter? Because an Allen key goes straight in from the top. It does not need side clearance. In tight electrical boxes, that side clearance is exactly what you do not have. The Allen key also gives you more leverage. You can crank it down harder, which compresses the O ring more, which gives you a better seal.

Key Feature

Rubber ring under the head

There is a rubber O ring sitting in a groove under the head. When you tighten the screw, that ring gets squeezed between the head and the surface. The harder you tighten, the tighter the seal. By the time the head sits flush, the rubber has filled every gap.

Which rubber to pick

NBR: handles oil. Good for engines and machinery.
Silicone: handles heat and cold. Stays flexible in both.
EPDM: handles sun and rain. Good for outdoor work.
FKM: handles chemicals. Use it where solvents are present.

Metal choices

304 stainless steel: does the job for most outdoor work.
316 stainless steel: is better near saltwater.
Zinc plated steel: is the budget pick. Good for indoor jobs.

Waterproof ratings

IP67: means one meter of water for thirty minutes. No leaks.
IP68: means you can leave it underwater longer.
