The Type Z designation denotes a slotted (spanner-wrench) style nut with symmetrically distributed slots that enable the balanced design — the nut is manufactured to balance grade G2.5 at 25,000 RPM, making it suitable for high-speed spindle applications on CNC machining centers, milling machines, and high-frequency spindles where vibration-induced runout must be minimized. The internal thread is the standard ER32 M39×1.5 metric thread, compatible with all ISO\/DIN 6499-compliant ER32 toolholders, and the nut is rated to a tightening torque of 136 Nm (100 ft·lbs) as clearly engraved on the face — applying this torque delivers maximum collet clamping force without overstressing the thread. The slotted OD accepts a standard ER32 spanner wrench or hook wrench for installation and removal.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;\"\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCollet System\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eER32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eNut Style\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eType Z (Slotted \/ Spanner)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eBalance Specification\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eBalanced (G2.5 @ 25,000 RPM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eOuter Diameter\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e40 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eHeight (Width)\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e12.4 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eInternal Thread\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eM39 x 1.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eMax Tightening Torque\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e136 Nm \/ 100 ft·lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eAlloy Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eFinish\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eBright \/ Natural Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCompatible Standard\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eISO\/DIN 6499 ER32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e87921320B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eAccutek\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"DDT and More","offers":[{"title":"Default Title","offer_id":49784973721815,"sku":"7235t8D","price":31.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/0626\/7095\/files\/accutek-87921320b-er32-collet-nut-1.jpg?v=1789404263","url":"https:\/\/dansdiscounttools.com\/products\/accutek-87921320b-er32-type-z-balanced-40x12-4mm-slotted-collet-nut","provider":"Dan's Discount Tools","version":"1.0","type":"link"}
