AIMS Industrial stocks taper pin assortment kits from Champion covering small and large size ranges for workshop, toolroom and machine maintenance use.\u003c\/p\u003e\n\u003ch3\u003eHow Taper Pins Work\u003c\/h3\u003e\n\u003cp\u003eA taper pin is driven into a tapered, reamed hole that passes through two or more components. The conical shape creates a wedging action as the pin is driven in — locking both components together with a tight friction fit. The self-locking taper means the pin will not back out under vibration or cyclic loading. Removal requires driving the pin out from the small end using a pin punch.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eTaper pins are used wherever precise, repeatable alignment and secure locking of machine components is required: gear and sprocket-to-shaft connections, coupling alignment, toolroom fixtures and jigs, machine tool spindle assemblies, and instrument and gauge mechanisms. They are an alternative to keys and set screws where a thin cross-section requires a compact fastening method.\u003c\/p\u003e\n\u003ch3\u003eChampion Taper Pin Kits\u003c\/h3\u003e\n\u003cp\u003eChampion CA1690 small taper pin assortment kit contains 140 pieces covering the small standard sizes.

Assortment refill packs allow individual sizes to be restocked without replacing the full kit.\u003c\/p\u003e\n\u003ch3\u003eReaming Requirements\u003c\/h3\u003e\n\u003cp\u003eTaper pin holes must be reamed to the correct taper — a straight drilled hole will not produce the correct fit. Standard taper pin reamers are sized to match the pin taper (1:50 taper ratio to DIN 258). Always ream the hole progressively and test-fit the pin before driving to the final position.\u003c\/p\u003e\n\u003cp\u003eNeed a specific taper pin size outside the assortment range? \u003ca href=\"\/en-nz\/pages\/contact-us\"\u003eContact our team\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2 id=\"paa\"\u003ePeople Also Ask — Taper Pins\u003c\/h2\u003e\n\u003ch3\u003eQ: What's a taper pin?\u003c\/h3\u003e\n\u003cp\u003eA taper pin is a cylindrical pin with a slight taper (1:50 standard) used to lock two parts together through a matching taper-reamed hole. The taper provides a frictional lock that resists vibration loosening. Used in mechanical engineering for: connecting shafts to hubs (couplings, gears, pulleys), locating dowels in precision assemblies, securing handle components. The tapered fit allows easy removal for service when needed. Available in metric (3-25mm typical) and imperial sizes.\u003c\/p\u003e\n\u003ch3\u003eQ: How do I install a taper pin?\u003c\/h3\u003e\n\u003cp\u003e1. Drill a parallel pilot hole through both parts using the smaller taper pin diameter. 2. Ream the hole with a matching taper reamer to the correct taper profile. 3. Test-fit the taper pin (should engage about 70-80% before becoming tight). 4. Drive the pin firmly into the hole using a hammer (gentle taps — don't deform the pin). 5. Verify the pin sits at the correct depth (typically slightly proud or flush, not below surface). Don't force pin too far — could damage the hole or the pin.\u003c\/p\u003e\n\u003ch3\u003eQ: Why use a taper pin vs a parallel pin?\u003c\/h3\u003e\n\u003cp\u003eTaper pin: frictional fit, resists rotation, easy to remove (drive out from small end), self-locking. Standard for hub-to-shaft locking and removable assemblies. Parallel (cylindrical) pin: precise alignment but doesn't lock — requires press fit or other locking. Standard for locating dowels. Match pin type to the application: removable locking joints = taper pin. Permanent press-fit alignment = parallel pin. The two can't substitute for each other.\u003c\/p\u003e\n\u003ch3\u003eQ: What sizes do taper pins come in?\u003c\/h3\u003e\n\u003cp\u003eStandard metric sizes (1:50 taper): 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm at the small end (large end is 2% larger over the length). Length range typically 16-200mm. Imperial sizes (1:48 taper): numbered #0-#10 plus inch-based sizes. For workshop replacement work, match existing pin dimensions exactly — wrong-size pin won't engage correctly in the existing taper-reamed hole.\u003c\/p\u003e\n\u003ch3\u003eQ: Where do I get taper reamers for taper pins?\u003c\/h3\u003e\n\u003cp\u003eTaper reamers are matched to specific taper pin sizes — must be the same 1:50 taper rate. AIMS stocks taper reamers for common workshop sizes. For specialty applications, individual taper reamers available on indent. For occasional taper pin work, hand taper reamers (with T-handle) work; for production work, machine taper reamers (with proper holder) more efficient. Always lubricate during reaming — taper reamers cut sensitive material and chip easily.\u003c\/p\u003e","products":[{"product_id":"champion-ca1690-taper-pin-small-size-assortment-kit-140-pieces","title":"Champion CA1690 Taper Pin Small Size Assortment Kit, 140 Pieces","description":"\u003cdiv style=\"max-width:680px;width:100%;padding:12px 0;font-family:Arial,sans-serif;\"\u003e\n\u003cdiv style=\"display:flex;align-items:flex-start;justify-content:space-between;border-top:1px solid #e0e0e0;border-bottom:1px solid #e0e0e0;padding:16px 0;margin-bottom:24px;\"\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e◆\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003ePins and locates assemblies\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e●\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003eChampion service-line stock\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e▲\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003e140-piece sorted kit\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size:14px;line-height:1.6;color:#444;margin:0;\"\u003eThis Champion Taper Pin Small Size kit puts a graded range of sizes in one box, for pinning and locating assemblies.
