M20 Conical Seat Washer DIN 6319D A4 Stainless Steel

M20 - Conical Seat Washer DIN 6319D - A4 Stainless Steel | Vital Parts

Our Stainless Steel Conical Seat Washer DIN 6319D, also known as Female Spherical Seat Washers, is designed to allow secure fastening even when surfaces are not perfectly aligned. These specialist washers are ideal for use where the mounting surface and fastener may not be completely parallel, helping to compensate for angular misalignment. Often paired with Pan Head or Cap Head Screws, they can also be used alone with Countersunk Screws to create a self-centring effect that enhances fastening precision and reliability.

This product has a concave internal face that accommodates the spherical shape of the mating component or screw, allowing for even load distribution and improved clamping force. Manufactured from high-grade stainless steel to DIN 6319D standards, these washers offer excellent resistance to corrosion, wear, and heavy mechanical loads. Available in A2 (304 equivalent) and A4 (316 Marine Grade) stainless steel, they are suited for both indoor and outdoor use. Metric sizes range from M6 to M24, making them a versatile solution for various applications.

What are Conical Seat Washers?

Conical Seat Washers, also referred to as Female Seat Washers or Dished Washers, are precision-engineered components designed to work with fasteners where perfect alignment cannot be guaranteed. Their dished profile allows for angular adjustment between the washer and the fastened surface, compensating for misaligned holes or uneven surfaces. When paired with Male Spherical Washers, they form a spherical assembly that ensures optimal load distribution and surface contact, reducing stress and enhancing the longevity of the fastening.
