DIN 127 spring lock washers supplier
XZ Fastener supplies DIN 127 spring lock washers for machinery, equipment assembly, maintenance kits, brackets, and general industrial fastening. These split helical washers are designed to provide spring action under a nut or bolt head and are often used where a simple anti-loosening aid is required. Carbon spring steel, stainless steel, and other materials can be supplied according to order requirement, with plain, zinc plated, black oxide, phosphate, hot dip galvanized, and other finishes available upon request. Buyers often combine DIN 127 washers with DIN 933 full thread hex bolts, DIN 934 nuts, and flat washers.

What Buyers Should Know Before Sourcing DIN 127 Spring Lock Washers
DIN 127 spring lock washers are commonly used under a nut or bolt head to add spring tension and help resist loosening in light to moderate assemblies. They are not a replacement for correct preload, proper torque, thread engagement, or engineered locking methods in critical vibration applications.
Before ordering, buyers should confirm washer size, form, material, hardness, finish, and whether the mating surface can accept the washer edge. In assemblies using metric hex head bolts, flat washers, and nuts, the washer sequence should be clearly defined. The XZ Fastener bolt, nut, and washer size matching guide can help purchasing teams prepare a complete size list.
Key Purchase Checks
- Confirm DIN 127 size, washer form, material, and finish.
- Check whether spring lock washers are suitable for the joint condition.
- Review bolt grade, nut grade, torque target, and washer sequence together.
- Confirm coating thickness where washers are used with plated or galvanized fasteners.
- Define carton weight, small box packing, palletizing, and buyer label requirements.

Material and Grade Explanation
Carbon spring steel is a common choice for DIN 127 spring lock washers because it can provide the elastic behavior expected from a split helical washer after proper forming and heat treatment. Stainless steel A2 and A4 options are selected when corrosion resistance is more important, such as outdoor equipment, damp environments, or appearance-sensitive assemblies.
When DIN 127 washers are used with Grade 8.8 carbon steel hex bolts, buyers should confirm that the washer material, hardness, and surface finish are suitable for the tightening method. Spring lock washers are often used with zinc plated DIN 933 bolts, black oxide DIN 933 bolts, and hot dip galvanized DIN 933 bolts, but coating compatibility and assembly torque should be reviewed together.
Assembly Performance Notes
- Spring washers help maintain tension only within a suitable working range.
- They should not be the only control method in critical vibration joints.
- Soft mating surfaces can be marked by washer edges during tightening.
- For important assemblies, preload strategy should be reviewed with the full bolt, nut, and washer set.
For technical background, review XZ Fastener guidance on lock nuts, washers, and preload.
Surface Finish Selection Guide
Zinc Plated
Zinc plated DIN 127 spring lock washers are widely used for indoor machinery, equipment, maintenance kits, and general industrial fastening. White zinc and yellow zinc can be discussed by order.
Black Oxide or Phosphate
Black oxide and phosphate finishes are often selected for machinery, fixtures, and appearance-controlled assemblies. Oil or additional corrosion protection may be required during storage.
Hot Dip Galvanized
Hot dip galvanized spring lock washers may be requested for outdoor fastener sets. Buyers should confirm coating thickness, washer function, and fit with galvanized bolts and nuts.
For coating comparison across bolts, nuts, and washers, review the XZ Fastener fastener coating guide.
Manufacturing and Quality Control
DIN 127 spring lock washer production requires control of forming accuracy, washer opening, section profile, inner diameter, outer diameter, spring height, edge condition, hardness, coating appearance, and final packing. Heat treatment is important for carbon spring steel washers because it affects elasticity and service behavior.
Quality checks can include material verification, dimensional inspection, hardness testing, spring form review, burr inspection, coating thickness testing, and final visual sorting. For broader washer sourcing guidance, buyers can review when split lock washers are suitable for industrial use.
