    Japan standard JIS B1183 Domed cap nuts Type 1 Type 2 Type3 for 4T 5T 6T carbon steel ZP YZP zinc nickel alloys 304 316

    Specification


    Scope:

    This Japanese Industrial Standard specifies the steel domed cap nuts (hereafter referred to as "steel nuts"), the stainless steel domed cap nuts (hereafter referred to as "stainless steel nuts"), and the copper alloy domed cap nuts (hereafter referred to as "copper alloy nuts"), all for general use for the characteristic.


    • Made from 304 stainless steel, these cap nuts have good chemical resistance and may be mildly magnetic. Also known as acorn nuts, these nuts have a smooth rounded head that covers and protects threads while providing a finished appearance

    • Made from 316 stainless steel, these nuts have excellent resistance to chemicals and salt water. Also known as acorn nuts, these nuts have a smooth rounded head that covers and protects threads while providing a finished appearance. They may be mildly magnetic.

    • Often referred to as acorn nuts, these nuts have a smooth rounded head that covers and protects threads while providing a finished appearance. About half the strength of medium-strength steel cap nuts, use them in light duty fastening applications, such as securing access panels.
    • Zinc-plated steel cap nuts resist corrosion in wet environments.
    • Chrome-plated steel cap nuts have excellent resistance to chemicals and salt water and have a decorative metallic finish.

    • Often referred to as acorn nuts, these nuts have a smooth rounded head that covers and protects threads while providing a finished appearance. They're about 25% stronger than medium-strength steel cap nuts and comparable in strength to Class 10.9 bolts. A zinc plating provides corrosion resistance in wet environments.

    Product Description

    The Acorn Center Lock nut machined from bar or if volumes and size allow, can be cold formed. Acorn locknuts are produced by installing 2 deflections in opposite flats precisely in the center the nut hex. Low Profile Acorn locknuts are not required to meet the thread start or torque requirements of Full Hex Center locknuts.


    Applications

    The Acorn locknut is used for either decorative purposes and/or to protect from scratches when surfaces would otherwise encounter exposed screw threads. Acorn Center locknuts are typically found in furniture, medical and recreational vehicle assemblies. Mating parts must extend at least one thread past the locking element to assure locking element engagement.
